This is childish already. Yes, what about the pixels?
"not totally supported", "generally not recommended", "by this forum", "I wish it removed", "take a closer look"
Are you gonna point out what would be that problem(s) with the 500uV/div, or just throw blanket affirmations while stating the hate for some random option? Pixels are not doubled, look at the sinusoidal waveform and you'll see plenty of one pixel. Averaging is like oversampling in ADC, together with the noise they increase the ADC resolution, therefore 500uV/div still shows independent pixels while averaging.
I found the 500uV/div very useful, for example I recently measured with it contact resistance, and found some shorted MLCC using a tape recorder head as a magnetic field probe for AC. It is also useful when reading measurements made by the scope, because those measurements are made by the displayed pixels, therefore in 500uV/div I can get more precise numbers.
Same when integrating the values while emulating a lock-in amplifier, the resolution is increased. The fact that there is no input divider for that range is irrelevant when averaging, and that is where having it enabled makes the difference.
To me, 500uV/div was useful many times already, and it works just fine, and I totally don't get it why some of you want it removed with such passion.
