Sorry about that! Forgot to change the sharing permissions on the new sheet. This project started at the end of in-game summer. (6/2020)
Right now, I've got decent data for routes 1, 2, 5, and 22.
You might notice I include "evening" as a time period. Short story long, a few days ago, when the servers were acting up, I *think* I hovered over the clock and it showed "evening". I had never heard of evening being part of the game prior to this. I did a little searching, but I could only find these patch notes mentioning evening as a period of time. I assume that, if I wasn't just too dang drowzy, that the servers having difficulties might have been related. I also figure it could have been a superficial error. At any rate, my sample size I shoot for is 100, which is pretty rough, but I wanted to go ahead and put in a little extra effort and double check. Honestly, I'm really excited to see how other routes pan out because from rt 1 alone, sentrets made up 11/100 during day hours and 23/100 during evening hours. Very likely just RNG combining with the small sample size, as I highly doubt there is a hidden 4th time period.
I also restarted the project to make sure all the data I collected was during unmodified weather, which is probably unnecessary. I've got a little extra general info that Rache was very kind to provide me with, which I intend to incorporate into the OP when I get around to it.
E: Whoa, Rt3 for sure has "evening" show up when I hover over the clock. Took this screenshot a minute ago.
