When I put in a tach tape with too small of stripes, some were ignored and I believe it started counting like every third stripe. I got a result that was opposite what I wanted. I think you can also adjust the flywheel diameter to change the speed. So a certain thickness of stripe would pass faster or slower?
It was a long time ago and I didn't make notes. There was a post here from Dave Hikel, on the limits and what works with the stripes. I'll search for it.
