Whats the Ratio for web Cam Sites?

[sizzlexxx]

I was just wondering I know that Cam sites have "rev share" or Pay Per Sign up. I know Sign up is your best bet.(This isn't what I'm questioning.)
I was wondering if you are PPS what the Member Sign up to Member pay ratio?? Because I know on many Cam sites it's free to sign up BUT you wont get your 35, or 40 dollars share UNLESS, the sign up ends up purchasing some time or upgrading to deluxe. I was wondering whats the ratio to Signing Up and actually Upgrading/paying??

I have seen quite a few sign ups on my buddies affiliate cam site but no turn around.Everyone only wants to watch . . not pay. . so whats the ratio???

Is it all just
