I know some people prefer CSV files, so here you go:

Out of curiosity, was the method used for division assignments changed for this year? These lists seem quite different from the live-updating prediction sheet someone made.

Edit: Did some quick crunching in excel; overall, just under 10% about 18% of teams are in the division the spreadsheet predicted they would be in., and for some divisions that number is as low as 2-3%. So definitely seems like something with division assignments changed.

(Edit 2: corrected my accuracy numbers, which were wrong due to an excel formula error)

Thank you for the CSV files, they are so much easier to copy into a spreadsheet than the documents on robot events.

looks like a little bit of your data is off; my team (2496y) was predicted to be in math, and ended up in math. (Your sheet says false) But you are right, definitely looks like something changed.

Thanks for pointing that out, I’ve fixed an error which was under-counting accurate predictions in the R, E, A, & M divisions. The actual accuracy of the predictions was around 18% on average.

They have always adjusted a few teams but I never figured out why. It’s possible that they would put some teams out of order in the pits due to language or some other reason, and that would then be reflected in the division lists.

That’s only slightly better than the 16.6% you’d expect from a randomized prediction. I guess the lesson is that unless your prediction uses the exact same algorithm, you’re no better than a monkey throwing darts. Although that sounds pretty entertaining.
