Mine reads about 105 and the GPS says 95ish... on a 2 mile run on the Soo RR grade, so GPS was accurate. I think 10% is considered the norm.

I was on the river a couple weeks ago and I think I had track slippage because I was over reving to about 8800.....but mine says about 106 and I have 96 on the GPS.
