LOL, you are certainly not "'self promoting'"in my view, however, I do know from past reading that resource are limited. Yes, direct from the Admin's (owner) desk. I suspect that to track minutes for millions of caches it would be prohibitive when trying to render. Response time is a priority especially for paid members. I would not want to start it and have to step away for an hour only to come back and find it is still rendering.
Sorry, I didn't want to post this back when you first asked because I figured someone would pick up the baton and run with it. If I am wrong on my theory, I apologize.
