Scoring formula used by the PWCA in the 2011 season: 
* GAP, but with only Leading, Time and Distance points
* standard GAP day quality, with additional nominal launch parameter to reduce influence of a few non-launchers on launch quality
* slightly different leading coefficient calculation (distance^2 instead of distance) to reward leading out early in the task
* PWCA stopped task rules: 
  * Score-back by 5 minutes
  * Bonus distance based on altitude at stop time
  * time window for elapsed time races or races with multiple start gates
  * pilots between ESS and goal are scored for whole flight
  * time points reduction for all pilots in goal (equivalent to pilot crossing ESS exactly at stop time)
