How long or how many 5gal batches do 5lb and 10lb CO2 tanks last you guys?

Asking because everyone's saying the 4912 can just fit the 5lb tank, and I was thinking of going with this one. Wondering how often I'll have to refill it.

I'm on my 7th keg with my 5lb co2 tank. I think it's pretty close to empty though. I use co2 to carbonate and serve.

I think it averages to about 10 corny's from a 5lb CO2 tank, assuming no waste, no leaks.

by waste i mean "carb pressure is the same as serving pressure...you won't be turning off CO2 and venting the keg a little to get down to serving PSI"

its a lot easier to just get longer beer lines, than venting all the time.
