Position - should this be happening?

I decided to look at one more thing and it tends to say the problem is not lack of respect for button raises.

EV when raising in cutoff : .403 big bets
EV when raising on button : .691 big bets

"But it could also mean that opponents (those particular oponents -- at PP? online in general?) are suspicious of the button steal and are calling into the button's raises more often they they should while respecting the CO's raises relatively more. Perhaps it's an indication of increased "sophistication" among online players."

If he is leaking money from the button, then it seems the answer is rather that opponents do not call a cutoff raise often enough. If they were calling "too many" button raises, that should result in more money, not less.
