> I know it’s thermal throttling because I can see in iStat Menus that my CPU usage is 100% while the power usage in watts goes down.

When I read this I wondered "Why isn't core temperature alone not a reliable indicator of thermal throttling?". Isn't that the state variable the thermal controller is directly aiming to regulate by not letting it exceed some threshold?

My M4 Max Macbook Pro can run for a while at like 105°C and fans to the max before throttling, when it starts throttling it doesn't exceed that threshold, and then the temperature goes down for a while before throttling stops
