Yes maybe. It's an opportunity to shape the event. As a rulebook event it would possibly gain participants in new venues.

It's a great event, and part of evolution, which we need.

Go to gliderscore.com. I just shook the synapses loose and remembered
the site. The program is already set up to generate the matrices you
described and to specifically score F3K comps.

I've been evaluating it for other uses and will publish an article
about it soon.

Happy Landings,

Re: Re: F3J Flight Matrix Calculations

If you do Jim, give it another name, not F3J, make it F3W, F3J is for human

Go to gliderscore.com. I just shook the synapses loose and remembered
the site. The program is already set up to generate the matrices you

I've been evaluating it for other uses and will publish an article

calculate a factor to use in determining the variance in the matrix and run
1000 trials and select the one with the least variance. To do this I
compute and record how many time each pilot flies against the other pilots.
For each pilot I compute the standard deviation of these numbers. I then
add all the pilots standard deviations together and compute the average
standard deviation for the entire matrix. I pick the matrix that generates
the lowest standard deviation in 1000 trials. Generally I see a minimum
standard deviation of about 1.28. Some individual matrix SDs are 1.9 or so.

distributed flight matrix developed. He says that it uses a program similar
to one he designed to do just what you are attempting to do. Goal should be
to get each pilot to fly against other pilots an even amount of times. So
the software has to check for previous pilot matches and throw out
recurrances.

events and handle all the matrix and scoring tasks. In the past I have
always generated the flight matrix using a random assignment and rarely have
any complaints. However, I am now looking at generating the fairest
possible matrix for the US F3J Team Selections and have run a number of
tests and often see anomalies in the matrix where a pilot flies against
another an inordinate number of times or very few times. I ain't the
sharpest pencil in the box, so I could use some suggestions on how to
improve the matrix from some of the smart math people in the group. I am a
programmer so if I understand the algorithm I can program it.. :)

every pilot has a fixed pilot number between 1 and 4 (including BYES). I
then compute a random sequence of the position numbers 1-4 and assign the
flight group based on that sequence. Repeat for each team. When all teams
have been computed for a round I go on to compute the next round.

calculate a factor to use in determining the variance in the matrix and run
1000 trials and select the one with the least variance. To do this I
compute and record how many time each pilot flies against the other pilots.
For each pilot I compute the standard deviation of these numbers. I then
add all the pilots standard deviations together and compute the average
standard deviation for the entire matrix. I pick the matrix that generates
the lowest standard deviation in 1000 trials. Generally I see a minimum
standard deviation of about 1.28. Some individual matrix SDs are 1.9 or so.
