I have done an early morning performance measuring takeoff with the
wing tip on my assembly stand. No wind, slightly one wing low, and
off we went. Of course, the 604 has enough inertia in the wings that
it won't do anything fast in roll! Canopy fog over was another
story. Never lost site of the tips of the towplane.

And if you actually read Evan's post, he said he has the tip wheel,
but it was not where he was when he started the retrieve.
