I'm not really pushing enough traffic ATM to go by 5K per site, but since a great deal of my traffic comes off my LL I get to promote every site for a given sponsor. I think based on what I've heard I'll move my cutoff for a program up to 12k hits.
Kinky: My personal opinion, if I've got a sponsor that goes 0:6000 I drop them like a bag of lit dynamite, but I go to at least 6k since I've had sponsors not convert at all then got a shitload of sales in a short period, bringing their overall conversion ratio to a respectable level.
Bare: I don't personally consider time frame, but I can't speak for others
