RE: SPA / BPA prediction
I really didn't mean to open a can of worms, although the discussion for the most part is very enlightening.
My thought on this thread was to discuss how the SPA and the BPA could co-ordinate to provide contests with more "critical mass" of fliers.
Back in the day, a normal pattern contest had about 40-60 fliers in 5 classes, at least here in the NE.
