It’s late in the season, but I haven’t seen this discussed anywhere. There appears to be a significant discrepancy in the Game Manual between the text that describes where an AprilTag goes, and measurements shown in the accompanying illustration. This is from the current on-line version of the manual.
Yes. I seem to remember a general rule somewhere that if there is a discrepancy, the written text rules. That said, I looked at the picture, and set ours up wrong. No huge deal.
