Yeah, I tried to mention that too, but it's hard to picture if you don't see a waveform and/or understand what causes heat. Not too many people know what slew rate is. So I didn't spend too much time on the topic. Basically, I was comparing the MM specs to the R1 Pro spec outlining the substantial difference in the resistance since those are noticeable numbers.

And yes, the higher the switching frequency, the harder it is to get a perfect square wave.
