and grants that several are worthy of consideration, but closes
with a cautious acceptance of Propulsive Lift, in which Newtonian
reactions to diagonal sculling strokes, rather than Bernoulli
forces, play the primary role. This is a partial repudiation of
Counsilman's Lift Theory.

believe. But, whether or not one agrees with Maglischo's
conclusions, I don't think one can dismiss his observations so
easily. He is clearly trying to resolve various theories with
these observations, not tailoring his observations to fit a pet
I trust Larry's observations as far as recovery, reach and maybe
even the catch, but I just don't believe he can see enough of
what happens beneath a swimmer from poolside, not to mention from
the grandstand, to speak with real certainty about propulsion.
Perhaps he can find a more recent "controlled study" in which
there are clear observations of propulsive motion that
complement his above-pool observations.
