The problem with getting faster on a unicycle is not normally the that you
can not push the gear it is that your foot can not move fast enough. I
know that I can ride a road bike at 30mph I know what the that feels like
and 16 or 17 mph feels similar on 110’s on a Coker in many ways.

The same ones but you are not stretching the muscles as much and the
critical bit is that there is less lateral force on the knees from wobble.

That is practice, I can ride 25% hills on my 110’s but is not good. I do
not suggest you go to the extreme that I have but shorten your cranks a
bit when you are happy to. do one step at a time.

Yes, it is a direct corrolation. Because unicycles are fixed gears they
make the physics a lot easier, I will get my old maths books out if you
would like and give you the formular (or someone else can). If you don’t
believe me look at the figures for the standard unicycles. Play with the
spread sheet until you get the same foot speed for each wheel size and
then go and ride each size, the feel is the same. Also if you look at what
the Japanize lads ride for marathen, 24" x 75 cranks, they have a similar
performance to a Coker.

Yes your foot speed is a lot slower as well.

I would have said it was you balance memory that was set for the bigger
wheel, the bigger the crank ratio the smaller the angle of balance is.
