Vision targets on team version boiler

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.

While it may not matter in calculating distance, it certainly makes a difference in recognizing the targets. Typically you want to determine that an object you have detected with vision is actually the goal, and to do this you want to be able to check the ratio of height to width along with other factors. The difference in width from the team version to the real field could be enough to make checks like these that worked on a team's field not function properly in competition without modification.
