John,
If the flaps being deployed caused a spinnaker effect wouldn't the wind be
traveling fast enough to be flowing backwards across the wing thus making
your glider drop from the sky like a rock. Flaps fully deployed should allow
your glider to fly at it's slowest possible airspeed regardless of wind
direction which is also the slowest possible ground speed for downwind
landings.

From the department of statistical analysis...
There were 700 landings attempted at the SWC.
483 had a zero
135 had a 25
62 had a 50
20 had a 75
0 had (or tried) a 100
A petri dish has a side to it; it's obvious that we could have used that.
Personally I enjoyed watching people throw flaps downwind and have the
same
effect of a boat throwing out the spinnaker. The plane would begin to
speed
up.
Mike Reagan pointed out something to me that I didn't figure out till the
5th round. Put your plane down on the time. Due to the triathalon scoring
the penalty on either side of the target time is extreme. If you are off
by
5 seconds, that is 35 points.
I was off by a few seconds compensating for the downwind. Attempting a
landing at that point isn't really worth it! If you had just put your
plane
down anywhere on the field, on the buzzer, and you made your time, you
would
have been in 10th place.

Dave,
The landing task looked like an 8-foot petri dish with 3 different kinds
of
fungus growing in it. In the upper right corner there was a 3 foot
diameter patch of what looked to be athlete's foot that was worth 50
points. In the lower right corner was a 2-foot growth of what may have
been trench mouth, worth 75 points. In the lower left corner was an
itty-bitty circle, well under a foot in diameter, that was most
certainly
ergot. It was worth 100 points. Anywhere in the big circle but out of
the
smaller circles was worth 25 points.
As far as I know, nobody got the 100. Upwind (which happened about 5%
of
the contest) the 50 and 75 were doable, although judging the slide in
that
cement with occasional soft spots that the AZ folks call turf was iffy.
Downwind or crosswind, which was all of the rest of the time, you just
slammed 'er in there and hoped the skeg would keep you out of the safety
fence.
