BA will keep scenes in storage for years before releasing. I have noted anywhere between 3 and 5 years (and sometimes even longer) from the time they shoot a scene to when it is finally released. Of course, BA won't tell you any of this. But a little detective work using open sources (eg. social media, work, school timelines) of the models, can generally give you an accurate timeframe. Compare that to Sean Cody and Corbin Fisher in their 'golden years' when it only took 2 to 6 months to release scenes. A really good example from BA is 'Timothy Blue' (redhead guy)...he looked far older and bloated at the time his scenes were released because they had been shot up to 5 years previously!
