VPIP SD / Orbit

[ThinkQuick]

Well I guess this is the right forum for this...

So assuming I have a 'good player' VP$IP of just under 20%, my question is how many hands should I expect to play (outside of the BB) in one orbit (10 hands)? Maybe this should be: What is the range of this number within 1 SD?

I think I have long stretches where I'm not sure if I'm playing uber-uber tight or if my cards are actually cold. So I'd like to try to play one or two hands an orbit, with a heavy emphasis on playing two...

How dumb is this?
