Wall singles
Facing a wall stops the lean and the forward drift at once, because the wall will not move.

Folding forwards on double unders
Like watching the rope. That is exactly what it is.
The cue
“Eyes on the horizon.”
What it looks like
The chest tips over the toes for the whole set.
Why it costs you doubles
A leaning body lands in front of itself and wanders, and the rope has to chase a moving target.
The fix
The drills for it, best first. The figure is the first one, at half speed — tap it to pause.
Tall singles
Singles with the ribs down and the body long, so the shape holds when the jumps get bigger.

Can the camera see it?
dulike can see this one only side-on.Film from the front or at an angle and it is reported as not checked — never as passed.
It watches your body, not the rope: a speed rope is a few millimetres across and faster than a phone records. Whether a jump was a double is estimated from your time in the air, and how it works shows every threshold.
Not sure this is you? Film 10–30 seconds of skipping and dulike will check — along with the other faults it can see, and the one to fix first.
