It's extremely tall for a small aircraft. The wake would probably be about 50
feet high.

Remember, the air around the wake is also being dragged by the wake vortex.

But at very slow speed. Even the downwash itself is moving slowly, only a few
knots. Any of the winds that one often encounters at altitude would be enough
to rapidly disperse it.

You have no idea of the altitudes or winds aloft at which most people
practice maneuvers in real airplanes.

Wind by itself will not "disperse" anything, it will just move it.

It takes turbulant air to disperse things in the air.
