Winning too much....

[jacki]

I play in a friendly home game once a week. Everybody knows everybody. $10 buy-in for .25-.50 hold 'em, with some Omaha and 7-card stud thrown in.
I consistently win at least $5, usually $10-15. (Not a lot of money, but it's huge considering the stakes). I've only lost money once -- about $5.

Do you ever purposely play badly in a game like this, so as not to upset your income stream?
I'm not trying to brag, the competition is ultra-weak, just wondering what you would do....?
