[NSRCA-discussion] Nats

[Ron Van Putte]

John and I had a discussion about this after he had a discussion  
about it with Mike Harrison.

We can get equal exposure in one session IF the two sets of judges  
observe the flights of all 38 Master class pilots.  Let's see now 38  
pilots times 10 minutes average per flight equals 380 minutes.   
That's six hours and 20 minutes.  Hmmm.  Kinda hard to cram that into  
a four-hour afternoon session and the pilots will each only have two  
flights.

Well, let's only fly four four hours one day and finish the rounds  
the next day.  Then we can start on rounds three and four and finish  
them the next day.  OK, we have equal exposure for all pilots and  
we've flown for three days.  Wait a minute - pilots will have only  
flown four rounds over three days!

Now the reason for the matrix method becomes apparent.  With it, the  
pilots get equal exposure to judges each day, BUT not all pilots are  
scored by all judges every day.  Compromise  is involved to obtain  
six flights for all pilots.
