[NSRCA-discussion] 2007 Masters... clarify on Item20

Mon Aug 14 22:44:14 AKDT 2006

Thus... an equidistant (15 meter...) straight line IS a part of each 
maneuver... and the start of roll and stop of roll CAN be used for center 
ref... (have to "backthink" from the start of the rolling for the segment 
length...)

All adds up.

And I've been not looking for long enough of a straight segment... possibly 
half my missed downgrades that I referenced in a previous post.
