[NSRCA-discussion] Unknowns

I set this up 4 years ago as a fun event for Sunday morning at our fall
contest here in Albuquerque. Scott McHarg has been designing the
sequences for us since the inception of the event. The sequence is
designed to be a K-Factor of about 55 in 17 maneuvers with the intent
being a difficulty level between Advanced and Masters. Landings and
takeoffs do not count. Each year Scott sends the sequence to our
perennial Chief Judge- Richard Lindberg. This year we passed out the
sequences at the Saturday night party to the six participants( 4
Masters and 2 Advanced). There is no additional charge to enter and the
only prize is the winner gets his name on the perpetual trophy.
An important part of the event is that we handicap the classes. Results
are calculated by determining the weighted average maneuver score and
adding 0.5 points for Advanced. 1.5 points for Intermediate and 2.5
points for Sportsman. FAI and Masters have no bonus. While It might seem
too difficult for Sportsman and Intermediate, we did have a second place
finish by an Intermediate pilot a couple of years ago and this year it
was won by an Advanced pilot, both placings helped by the handicapping.
