Having experienced this numerous times, I have until recently blamed myself thinking that Alright, I made a mistake (even if I was certain I didn't)
After reading this post, I went out a few rounds today, paying attention to the matter.
Three times I experienced this during the same round, at Olympic. I was very thorough and the last thing I checked before putting was the meter scale just to make sure it had not changed after reversed cam angle. I know for sure everything was correct, yet the ball stopped half way.
So yes, there seem to be an issue.
