    11Here is how the Lc coefficient must be calculated. Be careful because there are several particular cases...
    22
    3 The Lc coefficient is calculated between Start and Arrival only  or between Start and MaxDistance if nobody makes goal. (NOT between Takeoff and Goal)
     3The Lc coefficient is calculated between Start and Arrival only  or between Start and !MaxDistance if nobody makes goal. (NOT between Takeoff and Goal)
    44
    55Any pilot who did not fly (ABS, NYP, DNF) or did not correctly cross the Start line within the specified time, must get 0 or null Lc (please check what happens in Race in both cases) so to get 0 Leading points (please check, but I think numbers bigger than 24 are not accepted by the .DLL)
     
    2929Iv = the area in Km*s according to these two graphs:

     45The "Lc" data RACE needs in the !RcLeadingCoefficient field must be:

    8372where all the data are in km or seconds and are:
    8473
    85 PilotStart = actual start time of the pilot (if a pilot has more than one starts, the last one is the valid one)
     74!PilotStart = actual start time of the pilot (if a pilot has more than one starts, the last one is the valid one)
    8675
    87 FirstStart  = the earliest PilotStart among pilots completing the SpeedSection
     76!FirstStart  = the earliest !PilotStart among pilots completing the !SpeedSection
    8877
    89 SpeedSectionDistance = the length in km of the speed section
     78!SpeedSectionDistance = the length in km of the speed section
    9079
    91 PilotMissingDistance= the distance missing to get the Finish line (or Max distance)
     80!PilotMissingDistance= the distance missing to get the Finish line (or Max distance)
    9281
    93 PilotLanding = Landing time of the pilot
     82!PilotLanding = Landing time of the pilot
    9483
    95 LastPilot = the latest landing time inside the SpeedSection or the latest Arrival time, whichever the greatest. Remember that if the day is stopped LastPilot cannot be bigger than the Stop Time.
     84!LastPilot = the latest landing time inside the !SpeedSection or the latest Arrival time, whichever the greatest. Remember that if the day is stopped !LastPilot cannot be bigger than the Stop Time.
    9685
    9786
    98 FirstStart = the earliest PilotStart among pilots completing the
    99 SpeedSection; if nobody completes the speed section then use first start
     87!FirstStart = the earliest !PilotStart among pilots completing the
     88!SpeedSection; if nobody completes the speed section then use first start
