I don't want to tell you what your own proposal was, but I didn't
understand it that way!

There seems to be a certain confusion between what constitutes a valid
start and what part of the start cylinder yields full distance credit
under the new proposal. My understanding is that any valid start
under 07/08 rules is still valid under proposed 09 rules.

I do think that defining the "front" or "full distance credit" portion
of the start cylinder w.r.t. the center of the first turn area rather
than the first turn fix is a logical improvement.
