the pull ratio mismatch is known, obvious, documented, and the result of that mismatch is why rhurbarb posted here.
and do look up "Chain Pitch" soon, ok?
all modern bicycles use a 1/2" pitch... and most of the antiques too.
smh.
Somebody didn't read the webpage he was referring to. Other people's kids...
Next time, before leaving snarky comment, READ what the person is discussing. Or perhaps, better to remain silent...

So it's not really known if 10 and 11 speed MTB rear derailleurs use the same pull ratios or not.
Be careful with the bike gremlin charts, some of them are wrong, for example they show 11 speed road and MTB cassettes having different pitch, but I can tell you that they are both identical on mine. Even the exploded diagram shows identical spacer thicknesses.

3.1. Standards by number of “speeds” and manufacturer
Cassette standards differ by number of speeds, i.e. by the number of sprockets on a cassette. Generally: the more speeds (sprockets), the thinner a single sprocket gets and the more densely they are packed (less distance between adjacent sprockets). Distance between the middles of two adjacent sprockets is called “cassette pitch” (different from sprocket pitch, that defines adjacent teeth distance).
Here's the problem:
Of course, there's this addendum, but the table is still wrong because that's clearly not the spacer width or cassette pitch.
11 speeds
Sprocket width is the same as for 10 speeds, so 10 speed sprockets can be used, provided that 11 speed spacers are used.
Sprockets are 1.6 mm thick, spaced at 3.74 mm (road), or 3.9 mm (MTB).
For more clarity on this, see below the
comment by Nicolas Hanssens and the following four replies by myself and Nicolas Hanssens. I.e, based on my last measurement, and practical experience,
Shimano MTB and road 11-speed cassettes have very slight differences that don’t make a noticeable difference when it comes to shifting (
