BEST of the BETS

While checking through my value bets for todays racing, came across a
strange one.
I have O O SEVEN down as a fav. chance, on todays going soft(huh) has
run 4times winning twice, yealding to soft has run once won one, todays betfair
odds were 32 a few minutes ago, (red flag).
The only reason i can see is another false going report, OOS has run 4 times on
heavy going and only placed once.
Will not know till getting the time of the first race, but i think looking for
horses that act on heavy is advisable.
