First - Chagan you never cease to amaze me man!
Second - you guys are getting way to technical!
My dad has always judged his grilling by his coctails.
Steaks - Drink a side
Chicken Drink and a half a side
And so on...
The only problem is as he gets older and drinks less the steaks get more well done!
regardless you get into talking about thermo-whatsis's and spherical chickens you getting way too technical.
