I have come to believe that the game has become more dishonest over the past five years as the economy has soured and this is leading to the betting pattern you are noticing (and it's not just at Aqueduct!!). Insider's always have had an unfair edge but it was always most obvious and eggregious at the smaller tracks. I always avoided handicapping and betting the smaller tracks because of this. Now, however, I've noticed these patterns expanding into the top tier NY and Florida tracks.
They seem to be exploiting the betting pools by hammering favorites to excessively low prices and putting over more longshots with inexplicable form reversals after a concerted campaign of form darkening. Handicapping in this environment of deceit is becoming harder and less rewarding.
To conteract this creeping degradation I've become much more selective in the races I bet and carefully watch the tote for signs of insider moves. I suggest you do the same.
