I believe it's more relevant to examine the results using only those hands that were not folded. If the showdown was visible to PT (but you folded along the way), I think PT counts the hand you would have obtained using the full board. That's uninteresting, since you weren't in the pot.

Click the box & make sure each line shows you a profit. If any are negative, there's a big leak to be found. If all are positive, that doesn't mean there aren't things you can do.

Hope this helps.
