Just one more comment. The thing that makes the top pilots so good is
the ability to adapt the or even predict the conditions. They know
when to go fast and the know when not to. They know when they can get
low and when they shouldn't. How they do this is just basic soaring
skills but they somehow do it better than the 2nd place guy. I have
yet heard anyone explain how they do this consistantly. I suspect it
is just years of experience.

How to come in at the back of the pack I am a much better expert at,
but it is the same things that will put you there. Falling out of the
lift band and having to climb back up in the 1 knot thermal after
passing up the 4 knot thermal will lose you a lot of time. And staying
high and stopping often in really strong conditions with a large lift
band will cause you to fall behind as well. As you can see what works
one day may not work the next or even from one hour to the next. The
pilot that can shift gears at the right time and fly both of these
conditions best on the same day will win the day. The pilot that can
adapt on a consistant basis will win the contest.

The math of getting around the couse fast is pretty simple. Fly the
McCready numbers for the conditions and you will do well. You will do
excellent if you can fly the McCready speed for the next thermal
instead of the last one. Of course there is some art to find the
thermals as well.
