While I don't know the specifics of your particularly chosen examples, the process and numbers are very much real life. So yes, that's how a $2.4 million dollar launch actually can equal roughly $22k for 2 months worth of work (for 2 CB partners). Not bad... but $11k per month of work is very different picture than the $2.4 mil that many interpret.
OH and in the off chance that the merchants in your example did NOT use 12 month projections and they did in fact close $2.3 mill in actual revenue (which I seriously doubt and I say that with respect), even then... when you tear apart the numbers, their payday would be in the $200k range. THAT of course is a great payday but still not $2.3 mill. Again though, I'm pretty sure projected figures were used as that's just become started practice with launches that have recurring billing.
