Good point!

Re-reading my own posts I came to the same conclusion this morning.

So it is possible to be in "good" tow position, and have the rope impart
a forward and downward pull (relative) to the glider!

20 degrees still seems like a lot to me. I guess it depends on the weight
of the rope, and the drag on the glider.

Only if the tow rope were straight. He has already said that it was in
a clearly visible catenary curve.
