Thanks Brendan.
The odds in the betting log are from Gruss Betting Assist, i.e. from the Exchange, at the time you receive the tip.
The odds in the betting log (on the website) are recorded by us approx 60 seconds before each race. They will rarely be the same, but should be in the ballpark, so to speak. We capture the aggregate odds via OddsChecker at start time -60 seconds.
SBC have done a write up on our approach to odds, which is worth a read. We generally slightly under estimate the prices (on purpose, we don’t want to over sell our profit/loss numbers).
