I'm figuring that I could, at best, keep four or five computers going continuously before I'd hit the wall on data entry.
Well, each CD was taking about a half an hour... So let's assume one finishes up every two minutes (evenly distributed.) I'd say 10 out of those 15 will be in CDDB properly, 3 will need some touching up, and 2 will not be in at all. That seemed to be enough time to get all of that done... Obviously there was some "idle time" where a disc was finished and I was on another PC entering data or switching discs or something, but I pretty much kept 'em busy. If I have to re-rip (and I will some day) I think it'll probably take a little longer (I was using CBR before, VBR tends to take a little longer.) But it's a decent system.
