Bear,
No doubt 91 and 92 boys did extraordinary....but 94 boys placed 3 kids in the region pool.
So the disparity between girls success and boys success is magnified by those two age groups, not determined by those two age groups.
And I struggle to think that more high quality girls aren't playing ODP than boys.
All the same issues/reasons/distractions apply!! Plus boys have to deal with USSF Academy siphoning off players.
