I assumed as much, I’m just wondering what exactly they did. For example IIRC some phone company would detect that a benchmark was running by checking for the program name, and then allow the clock to boost higher (increase thermal limits) if it was a benchmark (like you could literally avoid the cheating behavior by changing the name of the program being run).
