Default US SSA/SRA Contest Rules Poll

On the poll I was confused by the explanation of question 8[?]
regarding using the last exit position of the start cylinder as the
scored start point rather than the point closest to the first
turnpoint.

I understand the concept of the proposed rule change. The explanation
seemed poorly written and confusing to me.

The description said something about exiting out the back, then flying
through the gaggles in the start cylinder. I don't understand this
because if you did this then by definition you pass through the start
cylinder again and then have a restart on the 2nd exit right?
[start=last exit of start cylinder]

Why did we not have a choice to change the scored exit point to
anywhere on the front 180° of the start cylinder? That seems like the
best of both concepts with the fewest problems.

If the principle of giving a pilot his best score is applied, and
speed achieved after
exiting the back and then flying across the cylinder (on a street of
through a "boomer")
at a speed that exceeds the rest of the on course speed for the
flight, a pilot can improve both
his speed and his score.
This is a significant safety concern and likely to happen. Where elso
do you have lift so well
marked as the prestart?
Limiting to the "front " 180 solves this but has computation issues
due to potentially significant
variations in the heading of the first leg.
Wanna take a swing at trying to write some language to deal with these
considerations?
This is a good example of something that seems very simple actually
not being so simple.
Thanks for you thoughts.
