Windows pointer speed relates the that 'some' distance moved for each count mentioned in the prior question. The reason 6/11 is accepted as the right setting for gaming is that here the multiplier for that 'some' distance is 1, and 1 x anything is itself so this means the data coming from your mouse to motion in non-raw input games is as if windows wasn't messing with the data (even if it is still adding a slight delay/packet loss which is why raw input is the better option).
But 6/11 isn't the ONLY correct option as lots of places seem to state: here is the list of acceptable ones (this post has further correct options but they involve registry edits).
Control panel notch:
6/11 --> 1x count multiplier
4/11 --> 0.5x count multiplier
3/11 --> 0.25x count multiplier
2/11 --> (1/16)x count multiplier
1/11 --> (1/32)x count multiplier
Why are these valid options? Well you can multiply all the multipliers by a integer to get back to 1x because they're all fractions in the form 1/n
What this means practically is that even with these options you'll never miss an equivalent spot where 6/11 would be correct, so no skipping.
This means if you use a higher DPI for games to be more precise (skip less angles) but it means your desktop sensitivity feels too high for you, you can chose one of these options to get it back to a desktop sensitivity you'd prefer.
