You do have to be aware of how high the Counter can count and provide for wraparound if resolution makes that a potential problem.
Counter Reset can be used when the shooter is turned off or first turned on, i.e., before or after the count integrity matters.

Also, it should be made clear that a crude filter and a loss of resolution is being applied by converting the Counter to RPMs before doing the tests.
My preference is to do all processing and comparisons in native units and only convert to RPMs for the human display.

Bunniy, your Counter initialization in Begin.vi looks fine.

See, you get your license and immediately you're doing errands.
I have literally tried so many times to just get my wheel to my desired rpm. Can you show me or help me in anyway to get it to work with my photosensor
