Just a comment about the robot: that flagholder looks like CPVC water pipe, not schedule 40 PVC. While I wouldn't worry about the distinction between CPVC and PVC, water pipe is sized similarly to copper pipe, and therefore probably won't accept the stopper for the lap counter (which fits the nominal 0.5 in schedule 40 pipe).

We used to allow that stuff through inspection when schedule 40 wasn't called for by the rules, but now that it is, and because the lap counter has to fit, I would suggest that you replace it.
