Large chunks of meat are best done by temp. A brisket, for example, can look the same if the internal temp is at 150 vs 210. One is pretty much inedible. Same for large chunks of pork. You want to cook these to where they are tender, but not dry. For brisket, that is normally around 203-210 when measured at the largest part of the flat. You would just be completely guessing without a good thermometer.
