Decent version of the formula. Seems to work alright for a couple different temperature ranges. Averaged around a 12lb turkey for about 4 hours to try and get it to 175 F. 

The cooking scale is not perfect. It needs some kind of variable to prohibit super slow cooking. Fast cooking burns the skin, so that works out.
