Yep, I disregard my "table image" or only give it about 10% credence. Late in a tourney it doesn't seem to matter because there are too many other pressures and tactics going on with everyone at the table. People just ACT! They don't think as much. Plus, like was already said, maybe 2 out of 10 players even notice. Hell, even you said you were playing other tables. When people only look when it's their turn to act they have no idea what anyone's table image is. And with the turnover with online mtt, it just takes one new person at the table making a call.

Don't sweat it. I used to lose sleep over hands. I don't anymore. You do the best you can with the information and instincts you have. And you learn as you go.
