This works, but may lead to rust. Another possibility is to put a different
clamp on there. If you aren’t making frequent changes in seat height, try a
strong BMX clamp.
I never heard of “Showtime” as a uni brand, so I don’t know what we’re dealing
with here. Does it look like any of the unicycle for sale at www.unicycle.com?

Low pressure will help in the early stages. Higher pressure makes the uni more
prone to twist, and if the rider is still clinging to a support, she will tend
to twist toward it. But the higher pressure also lowers rolling resistance, and
makes learning to steer the unicycle much easier. If she’s riding on her own,
the higher pressure should be better, and she just needs a little time to get
used to it. Don’t worry, her balance didn’t “worsen”, but the ground contact
area of the tire got smaller, so it might feel that way.

It’s possible you went a little high, but it sounds like the usual initial
reaction of people when raising the seat from too-low to the proper height.
There should still be some bend in the knee at the bottom of the pedal stroke.
Now the legs are being used more efficiently, and she should be able to practice
longer without getting tired. Again the difference may not be noticeable if she
is not yet riding on her own.
> a) is the seat placed in the crotch?
Yes. Where else would you put it?

I agree it doesn’t. Except for tricks like a side mount. If somebody wrote that
for a standard mount, I think they were being way too technical for a beginner.
The idea is to get that wheel under you, and ride away before balance is gone.

Angle is not relevant. Rider is standing behind. When the pedal is pressed down,
there should be enough rollback to bring the wheel under (and slightly behind)
the rider. Adjust pedal height until you get this roll.

Many people learn this way, but it leaves you stuck in the “dead spot” and it’s
very hard to ride away from there. Also, if the seat is adjusted to the proper
height, you need to do something to get you up there. Rolling the wheel back
puts you in a position where the pedals are more level, and if done right,
you’re off balance to the front and must then ride away.

Jumping comes later (jump mount). I think you’re getting too much into theory
and not enough into practice. A video would be nice, but I’m not sure how easy
it is to get a PAL one (assuming you are in Holland?). Go out there and bang
away at it until it works. That’s how most people learn it, unless they are in
clubs or learn from friends.

Some of the most basic riding techniques still don’t have good instructions on
the Web. Sorry about that.

Scratch that itch! You can ride too.
