Twodogs, thanks for that, though so far I can only figure out the present months archives, which is better than nothing but not enough. So far "of course" it looks like IAS (surprise, surprise) deletes the top payer of the three totes and then pays slightly higher than the best of the other two, which is USUALLY significantly LOWER than the best tote (which USUALLY just happens to be NSW or Supertab)

Which means that you would be far better off with Sportsbet.

Further investigation (I'm still on with it) looks like also highlighting that when they do pay higher than all 3 it's on outsiders NOT on the fancied runners (SURPRISE, SURPRISE)

But credit where it's due they do pay Top Fluc up to 45 mins b4 the race which is better than most. (win bets that is)
