The samples parameter on the Sampling tab of the mantra ROP. More pixel samples will produce more ray marches within that pixel leading to higher quality. Using more pixel samples will also improve antialiasing and motion blur quality for the volume.

The Thought Space Athletics' Mantra is the first fairway driver from TSA. The average player will find it to be easily controllable with the ability to shape lines with it and get effortless distance. More advanced players will find the Mantra to be a great hyzer flip disc or perfect for rollers.

The Mantra is a moderate speed driver. I would give it a speed rating of 10 as it is comparable to the Innova Beast. The rim of the Mantra is thicker than a traditional fairway driver but not so thick that it would be classified as a distance driver by most companies.
The Mantra is the debut disc release from Thought Space Athletics, a company focused on beautiful, unique designs and quality disc golf products for all players. The Mantra will fly straight at a manageable speed for new players but will have a more understable flight for experience throwers. It can be used for precision drivers or for anhyzer lines and power rollers. It's an all-purpose driver with great glide that feels and flies wonderfully.

To Patrick McQuown, an adjunct lecturer in Brown's School of Engineering, that sounds like an appeal to entrepreneurship, and Uber itself has referred to drivers as "transportation entrepreneurs." McQuown and Brown professor Barrett Hazeltine, who co-teach an entrepreneurship class, thought taking a deep dive into Uber's business practices would be a good chance to teach students about entrepreneurship in the sharing economy.
So McQuown and a group of 89 students from the class performed a case study of Uber's driver model, which the students compiled for their final class project. The results were a bit surprising. They conclude that Uber's business model for drivers might not be as entrepreneurial as it seems.
Patrick McQuown and students take a ride in the car McQuown used as an Uber driver.McQuown ended up logging about 400 hours and 8,000 miles behind the wheel, documenting his experience along the way. When the semester started, McQuown and Hazeltine asked for students join the project. The 89 students who signed up split into teams and interviewed more than 100 Uber drivers to bolster McQuown's firsthand account.
The idea of Uber entrepreneurship starts to break down with the driver rating system, the research suggests. After every trip, riders have the chance to rate drivers on a scale from one to five, with five being excellent. Rating systems are the linchpin of sharing economy companies like eBay and Etsy, providing buyers a means of knowing who the best sellers are. Buyers are more likely to do business with top-rated sellers, and they might even pay a premium to do so. In other words, the ratings give sellers a chance to differentiate themselves in the marketplace. But that's not the way the ratings work with Uber, McQuown says.
"Entrepreneurship means that you create a product or service that's unique in the marketplace and you're rewarded with more profit," he said. "You simply can't do that as an Uber driver. There's no real chance to differentiate yourself financially from other Uber drivers."
Riders can't choose their drivers based on ratings, McQuown says, which means higher-rated drivers don't get any additional business. And higher-rated drivers don't earn a premium for their superior service.
That was McQuown's experience. He became a top-rated driver in his area, but his income didn't increase. Interviews with other Uber drivers suggest that experience is not unusual. "I am a top-rated driver in New England," said one driver quoted in the report. "I know because I received an email notifying me, and I receive no compensation for that."
And higher-rated drivers don't receive more in tips either, the team says. There's no option in the Uber app for riders to tip drivers through the regular Uber payment system. If a rider does want to tip, they need to do it in cash. They rarely do.
The work also suggested that the Uber model limits drivers' ability to make their own hours. When a driver accepts a ride, they don't know where the rider is going. The trip could be a mile, or 100 miles. So a driver could be ready to end their day, when they are called for a three- or four-hour ride. A driver could turn the rider down, but they risk a poor rating. It happened to McQuown on several occasions.
"The negative elements of being an entrepreneur are present," said Brown junior Constantin Wedekind, referring to the fact that drivers have to set their budgets and pay for upkeep on their cars. "But none of the benefits are there."
