I just realized my SOT (screen on time) is wrong. I had reverted to a previous backup and Tasker did the math like it was supposed to. I rarely go over 300. No I'm not on my phone that much, I have my screen stay on whenever I am driving and using maps (and plugged in). I drive a lot.
Many (maybye most) of those values are coming from a Raspberry Pi and multiple other Android devices. This isn't just trivial data being displayed, I refer to this screen quite often and many of those "tiles" are shortcuts to Tasker tasks. The "tablet" ones open Tasker scenes that give me options to check kids' tablet batteries, active apps, notices, shutdowns. The "garage" ones open a scene to control the garage doors, and yes those tiles are updated anytime the door state changes including date/time stamp. Tapping anything that contains a temperature sends an SSH to the raspberry pi to report current conditions in that room or fridge, though that is already happening every 10 minutes. The three different "alarm" tiles do what is shown or launches the alarm app. The "last toast" is very handy for those times some app shows a toast and it goes away before I can read it. Tapping that tile copies the last toast text to my clipboard so I can save, share, or read it again in another way.
Once I find a cool feature of Tasker/Raspberry Pi, I tend to go overboard with it.
