The 4-3 schedule remains the go-to 60/40 parenting plan that experts recommend for co-parents with children of all ages. Of course, co-parents can always modify when the schedule starts and add in midweek visits.
Yes, experts consider 60/40 a form of joint custody, specifically physical custody. Joint physical custody means that both parents share time with the children. In 60/40, both co-parents spend considerable time with the children.
60/40 can constitute primary custody, but it depends on the laws in your jurisdiction. Check with a local expert to determine whether 60/40 gives primary custody to the parent with 60% of the parenting time in your situation.
In a 60/40 custody arrangement, the custodial parent is generally the co-parent with 60% of the parenting time. However, this designation can differ depending on the state or jurisdiction. Seek guidance from local experts to determine whether your plan will have a custodial parent.

The M-6040 paver is designed to be the most versatile and productive concrete slipform paver on the market, featuring a unique dual telescoping main frame and variable width paving mold. It easily adapts to changing widths for maximum cost-effectiveness and flexibility.
The M-6040 paver is the only paver in the industry that can extend from 8 ft 3 in to 16 ft 5 in (2.50 m to 5.00 m) wide without the need for frame or mold inserts. For larger paving projects, the main frame can fully expand to accommodate additional bolt on mold inserts and hydraulic vibrators, extending the paving width up to 20 ft (6.00 m) wide in under an hour, without any additional frame extensions.
Update: (11/16/16) At the time of this review we did not have sufficient information to comment on HDR related issues. We have just posted an HDR Compatibility Survey which includes data on all Epson 4K-enabled projectors.The Epson Pro Cinema 6040UB is an all new 4K-enhanced home theater projector that replaces the earlier Pro Cinema 6030UB. Though there is only one digit difference in model numbers between the 6040UB and its predecessor, the 6040UB is a completely different projector, new from the ground up. Physically it is larger and six pounds heavier. It features a new light engine design, a new all-glass zoom lens, updated video processing capabilities, and of course its flagship feature -- 4K enhanced resolution achieved through pixel shift technology.The Pro Cinema 6040UB, priced at a retail of $3,999, is one of a family of aggressively priced 4K-enhanced projectors being released by Epson this summer. The other models include the Home Cinema 5040UB ($2,999), its wireless version the 5040UBe ($3,299), and the Pro Cinema 4040 ($2,699). In short, the differences are these:
- The Pro Cinema 6040UB and 4040 are sold by CEDIA dealers, custom installers and specialty home theater retailers. The Home Cinema 5040UB and 5040UBe are sold in open distribution and are available through Internet resellers.
- The Pro 6040UB and 4040 models come with a ceiling mount, an extra replacement lamp, a cable cover, and a third year of warranty included in the price. The Home Cinema 5040UB and 5040UBe come with a two year warranty; replacement lamps, ceiling mounts and cable covers are not included.
- The Pro models are black, the Home models are white.
- There is a performance difference between the 6040UB and 4040. The 6040UB is rated at 2500 ANSI lumens while the 4040 is 2300 lumens, and the contrast rating on the 6040UB is 1,000,000:1 vs 160,000:1 for the 4040.
- There is no performance difference between the 6040UB and the 5040UB.
The Epson Pro Cinema 6040UB and 4040, as well as the Home Cinema 5040UB, are marketed as "4K enhanced" projectors. They accept native 4K video signals and are HDCP 2.2 compliant. However, rather than using native 4K resolution imaging devices, they use 1080p 3LCD panels with a pixel shift technology that enables them to approximate the resolution of a native 4K projector. The big advantage, at the moment anyway, is that 1080p chips are much less costly than 4K chips, so these projectors cost MUCH less than native 4K products. The downside is that the approximation of the 4K picture is not as precise in detail definition as it would be if native 4K resolution chips were used.This approach to the display of 4K source material has been controversial. Many video purists maintain that the only "legitimate" 4K projection is that which uses native 4K resolution chips. They argue that projectors like these from Epson, as well as those from JVC which use a similar pixel shift approach, should be labeled as "4K simulation" as opposed to "genuine" or "real" 4K. (To be clear, Epson does not promote these products either as "native 4K," or the equivalent of native 4K, but rather "4K-enhanced." Epson publishes the native resolution of these projectors as 1920x1080.)Though pixel shift technology does not produce a 4K picture with the same precision that a projector using native 4K imaging devices can, it does substantially boost the apparent resolution of the picture well beyond standard HD 1080p, and it does so for a fraction of the price of native 4K machines. So until native 4K projectors drop to the price level of standard 1080p, there will definitely be a place in the market for pixel shift technology. How Does Pixel Shift Work?Though there are technical differences in how vendors achieve the effect, the basic concept is simple. An image is projected onto the screen with an initial scan of the 3LCD chips in native 1920x1080 format. Then on the next refresh of the chips the light in the engine is refracted slightly to cause the projected image to be offset by half a pixel to the right and upward. The system alternates back and forth, scanning between its native position and its offset position so rapidly that the eye can't detect any sequencing or overlaying of one image on top of the other. The concept is not dissimilar to interlaced scanning on a CRT where even and odd lines are painted in alternating sequence to achieve the full image.However, there is more going on than just overlaying two slightly offset discrete 1080p images, which by itself would just blur the image. The video processing blends and integrates the two images together, smoothing transitions and reducing or eliminating stairstepping and aliasing. The end result is a picture that looks much sharper than standard 1080p.This pixel shift technique effectively doubles the number of addressable pixels that the projector can use to define the image, from about 2.1 million in standard HD 1080p to about 4.15 million. By comparison there are about 8.3 million addressable pixels on a native 4K chip. So if one were to interpret this just by the math alone, one might say that the pixel shifted image is double the resolution of native 1080p and half the resolution of native 4K. But this does not tell the whole story.In actual practice, the eye does not perceive an 8 million pixel image to be double the resolution of a 4 million pixel image when viewed from the typical viewing distance in a home theater (usually somewhere between 1.0 and 1.5 times the screen width). Due to the limitations of the eye's ability to resolve fine detail, there are rapidly diminishing returns at this level of resolution. From a viewing distance of, say, ten feet from an eight-foot wide screen (1.25 times the image width), the eye can only see so much fine detail, whether it exists on the screen in close up or not. An eagle would be able to see it, but the human eye cannot. Once this practical threshold of image resolution has been achieved, one could boost the projector's resolution to infinity and all of the resulting incremental fine detail that you might see from a close examination of the screen would remain invisible when viewed from a distance of ten feet.Viewing Distance is Everything Think of it this way. If you are standing two feet from a 120" image, you can clearly see the difference between native 4K and 4K-enhanced 1080p. The pixel structure is smaller on the native 4K image and it more effectively resolves fine detail that is, by comparison, muddled in the 4K-enhanced picture. Now if you back up and increase your viewing distance, you lose your ability to see the fine detail in the native 4K picture, and you also lose the ability to see the pixel structure in the 4K-enhanced image. You've probably already had this experience when viewing a 1080p picture. You can see pixel structure when examining a 1080p picture up close, but as you back away there is a point at which you can no longer see the pixel structure--you just see what looks like a very clean picture. At that point you've lost the ability to see some of the detail--the pixel structure itself--that is actually in the image.Due to this phenomenon, there is some viewing distance at which you can no longer tell the difference between a native 4K and a 4K-enhanced 1080p picture. And in point of fact, if you continue to back up to say about 3 times the screen width, there is another point at which you would not even be able to distinguish between native 4K and standard 1080p. Back up further still, and you can't see any difference between native 4K and 1280x720. One's ability to perceive resolution and image detail is a function of viewing distance.So the essential question is not how much absolute detail there is in the image. Rather, it is whether the projector is able to deliver enough image detail to meet or exceed your ability to see that detail from your preferred viewing distance. And this of course will vary. Some people have more acute vision than others. Some like to sit close to the screen, others prefer to sit farther back, just like everyone has different seating preferences in a movie theater. This will determine whether you can see any difference between native 4K and the 4K-enhance image from the 6040UB.So with that said, in our testing so far we are struck most by the fact that there appears to be so little difference. The 6040UB produces a remarkably precise 4K simulation. The difference between this image and native 4K becomes somewhat more apparent when displaying very complex still graphics with fine detail. The native 4K products definitely have a resolution edge with this type of material. But with video/film subject matter the differences are not nearly that obvious. Moreover, we are not seeing any problematic digital noise or other artifacts that compromise the integrity of the video picture. Overall the picture is easy to visually interpret as being within the expected performance range of 4K resolution as compared to native 1080p. High Res Graphics -- A Different BallgameThe perceived difference in resolution between native 4K and 4K-enhancement is more pronounced with highly complex graphics as opposed to video. If you plan to present high res graphics or dense, complex spreadsheets the ability of the native 4K projector to render the finest detail could become a decisive factor for the display of this type of material. Native 4K projectors have a more obvious performance advantage with this subject matter than they do with video, so the price/performance calculus changes considerably based on application.For this testing we used the Samsung UBD-K8500 4K Blu-ray player (see Amazon listing) as a 4K source. The test discs were the UltraHD 4K editions of Deadpool, X-Men, and Life of Pi. However, there is still a relatively small amount of native 4K material compared to the huge body of 1080p video on the market. So if you are like us, you'll probably be continuing to watching a lot of upscaled HD 1080p rather than UltraHD 4K. Both native 4K and 4K-enhanced 1080p have the ability to improve the apparent resolution of a 1080p source.
