How often do we cbet?

[rsliu]

Lately I've been wondering if I cbet too often. I'm 22/12/1.3, and my first action on flop after a preflop raise breakdown is:

raise: 2.4
bet: 65
call: 6.6
check: 17.5
c/raise: .45
fold: 4.4

Should I be checking more marginal flops?

Also, should there be a significant difference between how often I cbet oop vs. in position? I feel position is not a strong consideration when I'm cbetting and I'm starting to wonder if it should be.
