Specializing lap timer of motor race Gleichmaessigkeits Pruefung in Germany.
It developed by the request of Mr. Wolfgang Hustaedt living in Germany (based on Parallel Lap).

What is Gleichmaessigkeits Pruefung ?

  • A closed circuit is done 12 times and it plays a game.
  • The lap time of the second times is recorded. This becomes BaseTime.
  • The fifth 3 and 4 times, it runs to become the same time as BaseTime.
    One point is subtracted whenever lap time is different for 0.1 seconds.
    (decrease ten points a second)
  • The pit stop is done the seventh six times for the gas charge. (non-demerit mark object)
  • It is BaseTime measurement as well as times the 8th times.
  • It runs the 11th 9 and 10 times to become the same time as the eighth times.
    (demerit mark object)
  • The 12th times are the out laps. (non-demerit mark object)
  • After it ends, the person with a little subtraction point is a win.
