I disagree. Depending on conditions, the pilot might need a
substantial amount of aileron in one direction of the other to keep
the forces neutral.

If I feel pressure on the wingtip while the slack is being taken up
then I allow the tip to go markedly high or low until the pilot
notices the glider is not level and applies the appropriate aileron.

That's what I like as a pilot, and that's how I will run a wing,
unless the glider pilot requests a different technique.

B.

I observed this example.

The pilot was holding full left aileron against a very light (2 - 3
Kt.) left crosswind component making the tip very heavy. The wing
runner, on the left wing, allowed the wing to go to the ground
whereupon the pilot jerked his thumb up indicating he wanted the wing
raised all the while still holding full left aileron.

The wing runner did his best but when the wing was released, it
slammed down and the glider ground looped. The pilot jumped out and
ran back demanding to know why the wing runner didn't know his job.

The group of observers tried to tell the pilot it was his fault for
holding left aileron but he insisted that was the right thing to do
and it wasn't his fault. He had a very hard time finding willing wing
runners after that.

My take home: If I were the pilot, I'd center the stick and let the
wing runner do the job right. If I were the runner, I'd just put the
wing down and walk away.
