When is it time to call a session quits even when you know you are playing your A game, but just can't seem to get anything going and are taking a beating??? Thanks.

As long as you play your A-game and feel you have an edge it should be correct to continue. The problem is (at least for me) that's almost impossible to be honest to yourself whether you play your A-game or not. Sit out an orbit. Your mind will get clearer almst the second your eyes moves away from the screen. Then decide.
