PC foam pads - how long lasts?

[supercharged]

This question will probably be more for a pro detailer. How long do foam pads lasts you guys/gals on PC? I know that it will depend how long you work that polish in...But let's say on average...Orange, white, and grey? What about Meguiar's pads?
Thanks in advance.

my lake country and excel detail pads wear about the same. cutting pads last ~10 full details, polishing pads last for ~30 full details, finishing pads i haven't worn out, I just throw them away when the product their holding can't come out anymore.

That's for large pads. Smaller ones don't last as long (but hey, that's mostly due to my backing plates melting on me and ruining the velcro backing of the pad)
