2023 team update 1 fixed two measurement errors - not conversion errors, though.
2022 team update 2 fixed the roboRIO image (not as the result of an update), similar to this year’s update 1.
I do get the general sense that there are a few more corrections in this year’s update 1, but I wouldn’t say that there are a lot more, and it could mean that fewer corrections need to be made in update 2.
Is there a way to see all of the updates made to the manual? I recall in previous years being sent a picture from a mentor of an updated manual with updates/corrections made in red. I checked the firstinspires website and didn’t see any markup like this.
