Quiet, I got these numbers from a really smart son of a bitch when I asked the same question
Exits, 60% (or so depending on how the exit pops) will view the exit out of the people that VIEW it 1:1500-2000 will signup. So if a company pushes 500k views to the exit that is around 250 signups daily
So if you're popping the console 150K times a day, 90K people will actually view it, and you should get 45-60 additional signups from that.
Marc De once said that the average is about 15 sales off the exits for every 100 sales to the site.
Most of the per sign up companies that offer console free tours pay $30 on those joins as opposed to $35 if they get the exits, and that's pretty close to a 15% difference.
Of course both of these scenarios assume your console will "filter" the traffic (i.e. give them ALOT of different options) as opposed to just popping up another paysite in the same niche.
