No hovering for the first several tanks in order to help keep the engine cool.

I disagree. When flying you have no way to know what the engine is experiencing if you dont have telemetry that includes temperature,RPM and load.Even if you do the chances are it will be too late to do anything about it.
With a good instrumented test stand you have much better control.
