This is oversimplified - there are more factors...
But - what is your experience level? What $ level are you playing?
I am going to take a stab and say you definitely need to be under 20% VPiP, and more likely under 15%. I was profitable month to month in low stake tourney's and was running about 13-16% (but you need to understand that the first 1/3 of a tourney I'd be at about 6-8% and open it up more as it went deeper).
Does that help?
