Charcoal heat guide

[PorkPatrol]

Does anybody know of a good chart or data set that shows heat output and duration based on method (snake, minion, etc), type, number of briquettes and vent positioning?

I'm going to start compiling this data on my own but I don't want to reinvent the wheel either!

If this is something you'd all be interested in, I can think about putting something together.

Thanks
