Wherebouts should these figures be ideally to be profitable........ just want to know where i should be working towards??

It varies, its dependent more on your vpip. Lower vpip and you should have a higher wtsd and w$sd, higher vpip and those two should probably be a little lower.

Mt VP$IP is around 20%...... would 25% and 70% be where i'd wanna be roughly or more 15-20% and 75-80%....thats tough to do though!!

My won at showdown figure for full ring limit hold'em is almost always around 54% for any extended period of time.

Yeah I think that you are folding far too much, I don't know WHY you would want to aspire to folding MORE often. If your W$ is 70%, it means you are folding far too many winners. Sure, you're folding lots of losers, but you have to consider the pot odds. Folding a hand in a spot where you would have won the pot is a major mistake, in fact a much bigger mistake than making a few losing calls. If you fold in a pot with 4 big bets in it for only one more bet, you fold has to be correct 80% of the time.

Of course, make sure you're going to the showdown much more in larger pots than in the smaller ones.
