I'm shocked! Shocked I say!
I don't think the change between the field drawing and real field actually matters. I noticed it too but shrugged it off.

The only thing that changes when you wrap the tape around a cylinder with a larger diameter is that the camera is going to see it as, well, wider. That shouldn't really matter in any calculations though. You can already get distance based on perceived height of the tape, and now you've got TWO of them to average it out. When it comes to aligning the robot for a shot (once distance is known) you really only need to concern yourself with getting centered and for that calculation it doesn't matter if you've got a 22" cylinder or a 48" one. Center is center.
