Depends what you are counting. If "dribbles," then players probably get more than 94% done right. If "shots," then not. As for refs, I assume you are counting actual "calls" they make, not "non-calls" (which I would consider worthy of measuring if we are really serious about evaluating refs). Tonight, I may try to keep count of how many actual calls they make in comparison with ones where I would be yelling at them for making the wrong call (or chuckling that we got away with one). If I get to 19 without a bad call, then I will know to get ready.
