Is this graph all your
hands or just hands where you have one pair?
Whatever it is; It suggests that you are very aggressive and so winning a lot of pots through fold
equity but not winning the majority of pots at showdown.
I'm no HU expert but my basic understanding is that a LAG makes money because the red line goes up (he gets many folds) and that a TAG makes money because the blue line goes up (he shows down the best hand).
Not many graphs have both positive. They tend to be one positive and one negative but the winners have it such that the net is positive (that is their winnings).
I appreciate I haven't really answered your question but I just like looking at graphs.
