Reference the above flight from this last weekend. In late fall no
less. We had 7 private owner ships flying, but only 3 of us were
recording that day. There were some really fun flights by everyone.
Now back to the topic...

I submitted my flight but disagree with the optimization for the
flight. It appears that my start point is not the off tow release at
21:51:38 but rather some 10 plus minutes at 21:02:38. The distance
from my trace is approx 4.6 miles or 7.40 km. Now if I were to use
this as my start leg, and subtract off the last "optimized" leg of
3.74 miles, I'd have more distance points = 114.75, but less average
speed. I've tried adjusting the times on the OLC submittal page, but
can't get it to change. Since you don't get credit for your average
speed, wouldn't it be better to optimize for distance?

Anybody know how to get it to change? Or am I missing something?

And on a second note, is there some explanation for how to interpret
the statistics table. What do each of the columns mean? Some of them
are self explanatory, but I don't understand %Kurbel, Naufwinde, and
E? Does anyone know the equations behind the data? I'm guessing they
are related to thermalling, but I just can't figure them out.

Thanks!

You are missing the rules :-) There is a limit of up to six task legs
(start, five turnpoints, finish) in OLC classic, with deprecation of
the points on the last two legs for points. Have a hard read of the
rules. To get the longer distance you seem to be trying to get would
require adding another turnpoint.

A quick glance seems that OLC is doing a fine optimization. It moved
the start point away from your tow release (which it correctly
identified - the start of the blue trace on the OLC image) because
after release you fly in a direction away from the first turnpoint and
OLC is finding a point to use for the start that is the maximum
distance from the first turnpoint. Any time earlier will give you a
shorter distance around the turnpoints and a lower OLC score. OLC is
already optimizing correctly to give you the maximum number of
turnpoints and letting the short leg at the end incur the greatest
points penalty. Magic stuff.
