Meats are done only when they are cooked to the proper published temperatures. No excuses!
For certain meats such as pork butts and briskets once the meat hits its safe temperature then we use feel but only to judge tenderness.
We monitor cooking grate temperature for an indication when the meat may be done and to ascertain if we are cooking too hot or too low. For example, an 8 to 9 lbs. pork butt will take 7 to 8 hours to cook at 275 degrees. Knowing this helps with planning.
