Another tip is to turn the wheels 10 times.....it makes the difference between 3.45, 3.73, and 4.10 a lot more apparent when you're looking for 34.5 turns, 37.3 turns, and 41 turns respectively. Sometimes the difference between 3.45 and 3.73 turns when you're looking at the shaft turn is tough.

I would suspect 4.10 would give a bigger difference than what the poster's seeing....3.73 would be more likely, but I haven't done a gear swap in a few years.
