4kW admin limit of 7kW available SSA power is 57.14% of power budget.

SSA Calibration drive max is performed at 80% of available power per procedure [Characterization > SSA]

This fixes the SSA drive limit of 80% (0.8) once performed, but one is able to set reactive power fraction to further limit the available power by reserving it for phase feedback.

With 80% SSA drive limit, a value of 49.2% reserved for phase feedback limits the available power for amplitude control (aka gradient level) to 57% of the SSA power before tripping on overrange.
