4th street percentage?

[TS Clark]

Folks:

I'm just learning to play stud (or at least learning to play it correctly) and am curious if you more experienced hands could advise a newer player on how tight is right.

In hold 'em, you have a VPIP % you can look at if you're a Poker Tracker person. There seem to be some accepted standards for "correct" percentages for that. How about for stud? What percentage of the time should you be seeing 4th street (on average)? I try, per Reese's advice in SS, to only play pretty premium hands, but, like all new players, I'm sure I have some major leaks. I'd like to see where I measure up at the start of hands, however, since I know enough at this point to know that starting hand selection is REALLY key in stud (even more so than hold 'em or Omaha).

Any help, advice, or wisdom would be most appreciated.
