I
think all here will agree that a student can learn more in a long soaring
flight than in a short sleigh ride.

Sort of. I think that a primary student learns more in four 15 minute
lessons than in one 1 hour lesson. I find that the airwork comes fairly
quickly, take off and tow less quickly, pattern and landing takes longer
still. My club does mostly 3K tows and when a student is close to solo,
we still tend to do a bunch of pattern tows - that HAS to be right.
