uh Hank???
11.2.3.3 For completed tasks, the final leg ends at the Finish Point; any finish radius is subtracted from its length.
Sure you can use up another mile worth of time by going to the edge of the finish circle but the way i read it you don't get credit for that distance.
Unless you are flying the 1-26 Championships. They score to entry point of the circle. You can finish in the "back" of the circle. Now that SSA has adopted starting out the back like the 1-26's have done for ever, maybe its time the SSA allows finishing in the back too
