Proper % to see fourth in stud/8 MTT

[codewarrior]

What is a proper percentage for a TAG to see fourth street in a Stud/8 multi on average from beginning to the money? That it, how often should a solid, tight aggresive player be seeing fourth street from the beginning of the tournament to after the bubble? I'm still a stud/8 newbie, and am accumulating chips early, or playing too tight & accumulating crap, possibly folding too much. I'm finding that 33% may be correct? Discuss...

If this is the wrong forum, feel free to move it to MTTS. Thx,
