@JohanS, I think you have a generally correct idea, except for the 50% description.
If max is 60% power and min is 20% power, the difference is 40. 50% of 60 is 30, but the halfway point between 60 and 20 is 40.
If max is 100% (not a good idea) and min is 10%, the difference is 90, half of which is 45, while 50% of 100 is 50. Even if you add that half to the min, it’s now 55.
The simplest way to read it is that the max power represents how much the laser will output, and scaling is applied to that number. Max power = 60%, scale factor 25% means 15% of the laser is now applied. The minimum only means that the laser can reduce power for acceleration compensation and also to reduce power as required by the scale factor.
