Flush > Full House?

[dfscott]

I've been losing with full houses more frequently than I expect to lately, so I started doing some investigation into my PT stats. I discovered the following (stats are based on 11K hands):

Full House
Got it 70 times -- won 83% averaging 6.2BB/hand.

Flush
Got it 80 times -- won 89% averaging 7.4BB/hand.

Straight
Got it 70 times -- won 74% averaging 5.2BB/hand.

Trips
Got it 70 times -- won 83% averaging 6.2BB/hand.

(I threw the last two in there just for comparison.)

Is this a statistical aberration or representative of other people's stats as well? Intuitively, I would expect to win more with the better hands, but I'm thinking that the nature of the boat (i.e., requiring a paired board) might put people on alert and makes them more willing to fold. I also feel that I'm more confident betting agressively with a low boat than I am with a low flush, so it may be my poor play that is costing me. Perhaps I should be calling more and raising less w/o the nuts?
