Agree with Sean.
And have big problem with Johns thinking.
It is no fun to fly MAT with one or no TP !
It is no fun to fly TAT with huge circles.
It is not safe to be forced to land at the airport ,
after good finish.
It is no fun to fly without the water.(like would be no fun to fly without ruder)
It is no fun if task is changed 3 times (including after first launch)
It is no fun if task was called in the air by one of competitors.
Those some of our " Better rules" John.
