C-betting A/K/Q/J high boards

[JH1]

I was going to post this in the FR forum but thought it might be too noobish.

I'm wondering if you are more likely to c-bet a J/Q/ or even K high flop when you miss rather than an A high flop. It seems to me lately that I have been getting c/c a lot more on A high flops than the others. Are OOP villain's holdings more Ax heavy than other paint cards, taking into account gap theory? Of course this is player dependant, but say for the average 25/8/1.5 10NLer.

Also, does this change for 6 max?
