Just wondering, say on a scale of 0 to 10, where 0 means your fingers are just resting lazy in the grips and 10 meaning you're squeezing the life out of the grips, what would be the recommended finger pressure on the grips?

Also, I find it incredibly difficult to do both cupping and relaxing my finger pressure. If I cup I tend to exert a lot more pressure on the grips. While this somehow generates more revs more me, I don't seem to be able to play for extended games.
