you know there's no real answer. a paysite paying $25 per scene and starting with 25 scenes with 10 more bought for updates will take a lot less time than a paysite that pays $2500 per update and starts with 10 updates with 5 held back updates. add in that some paysite owners may buy a copy of an expensive CMS where others will update by hand and you have quite a difference in startup costs, not even counting that some people do their own design and some pay thousands for their tour.

and then different webmasters have radically different traffic generation or ways to get affiliates. some paysites make less than 5 sales per day where others make 100.
