Great sharpening job! How many degrees per side?
 
Rolls-Royce used 17 of them at the far tail end on the RB-211 (several variants). They were all dual element TCs as well, so 34 channels. We used it to detect flame out and a 100 degree spread on one of them would have been a shutdown. The main engine I worked on had DLE combustors without crossover tubes, so if one can went out it was... really bad. We could not afford a flame out on a single can or the turbine would come apart in short order.

You could also see it in the CO emissions.

Yeah, LM6000s are actually remarkably robust engines...takes quite a bit to kill one in most instances ;)
