To answer Andy's question on the distance calculation - I believe the
2008 Regional rules contained a typo an were actually scored without
subtracting the start radius (which i think would have been a weird
random act of math if implemented as written). I could be wrong on
that - I thought I heard it somewhere.


How are the scoring rules embedded in Winscore derived if not from the
published rules?

Section 11.2.3.2 has the Regional start anywhere rule for 2008. Thats
the scoring rules section. They missed that it was in two places.


Yup - that's it. I remember now the typo fix was called out in the
draft 2009 rules.

"10.8.6 The distance of the first task leg shall be taken as the
distance from the Start Point to the control fix at the first
turnpoint, minus the Start Radius"

"11.2.3 Scored Distance
11.2.3.1 Scored distance is the sum of the distance achieved on each
leg of the task (but no leg shall have a length less than zero).
11.2.3.2 ‡ † For all Tasks, the first leg originates at the start fix
(Rule 10.8.5.3)"

It's actually ambiguous because 11.2.3.2 speaks to where the leg
originates, but 10.8.6 speaks to the distance of the first leg. As a
practical matter I'm certain they did not subtract the radius in
WinScore.

Now we're in the weeds for sure.
