Like many of us,at one time or the other,on purpose,or by accident ,I've done most all.
Yes,there is one, now prominent, stickburner on the TV series that likes to cook thru at 275º.

I had been taught that the longer big meats stayed in the plateau,the better they broke down collagen and rendered more fat.
Thus, guys in Smokin's area would do large cooks down around 200º for 18-20 hrs.
There are some good comp cooks in the same area,that may start at 250º,move to 275º,and finish out at 300º+.
The same guys may only hold the finished meat for the traditional beef period of 20 mins,carve and plate immediately for turnin..
If it is close to overcooking,they may go straight to the cambro filled with ice,set in front of the RV 's A/C vent,plastic bag and go to ice water,etc-all to instantly stop carryover heat rising.
As Smokin' says"the window is very narrow".
Those cooks practice and know if you live by the flame,you may die by the flame.
There is one prominent cook/teacher that was a fine pork cook and had to learn to cook KCBS/FBA contests,which meant briskets.
He started cooking nine large walmart packers everyday to get his tenderness down and fed them to the busloads of tourists traveling I-75.
He needed speed,so he adjusted to commercial hot oven temps to cook..
