The final OLC League rules were just posted to the OLC web site:

The OLC League is a new feature for the US, and several other
countries. It is a speed competition between clubs with different
leagues for each country. It has been run in Germany for a few years
with very much success.

All clubs and all flights are automatically eneterd in the
OLC-League--there is no need for a separate flight claim. It is a speed
contest, where the best 3 flights are scored for every club each round
(the server looks automatically for the fastest average speed within a
2 1/2 hour window of every flight of each club), the 3 fastest speeds
(divided by the handicap index of the glider) will be added to get the
score for each round. The rounds are each 2-day weekend Beginning April
29 and ending September 3. There is also one 3-day weekend in June (see
the calendar in the rules document).

The club with the highest average speed from the 3 fastest flights gets
50 points for the weekend round. The second fastest club gets 49 points
and so on, down to the 50th club getting 1 point for the weekend. The
club having most points after all competition rounds is the winner of
the OLC-League for each participating country.

One requirement of the OLC-League is that flights to be scored must
take-off at the home airfield of the club. So each club must designate
a home airfield for the OLC League competition. We are assuming this is
the same as the home airfield of the club. But clubs that have multiple
home airfields, or that may want to designate a different competition
airfield, need to get that info to the SSA-OLC committee at
olcatssadotorg (or your country's OLC coordinator for other than US
clubs). We must enter this data by April 21, before the start of
competition for the year.

It is not possible to change the club home airfield after the competion
starts for the year. It is possible for a pilot to change club
affilitaion at any time during the year, however. So if you will be
flying at another location and want to claim flights for the local club
OLC-league, you will need to change your club by editing your user
profile. You can only claim flights to one club at a time.
