Sorry, I don't agree.

If the intent of the rule change is to prevent starts from the back
half there are better ways to do it.

The rule should define the "front half" as the semicircle of the start
cylinder that has its diameter normal to the line between the start
point and the first turn point. *A valid start would only be given for
an exit from the front half.

The valid start area is then fixed for all contestants regardless of
where they turn in the first area. *This valid start area is easily
visualized by the contestant without needing any special computer
software.

Yes, I do think it's an improvement. Your version is even better in
its simplicity.

I've never seen anyone start from the back of the circle, either,
though I've only flown a couple of regionals since start anywhere was
adopted. However I can think of a few contest numbers that I would
expect to see trying this, sooner or later. I'd rather *not* fly this
way myself, but probably *would* if it was necessary to be
competitive. I rather we had a rule that took away any incentive to
do this.
