A price quote for a horse on the Tote is the current dividend payout on the event of that outcome happening. This tends to be similar to normal bookmaker odds, and tracks the market in a similar way, but at any given time may be better or worse than a bookmaker's quoted odds. However, since all bets are pooled, all bets are essentially "starting price" (SP), that is, until the race has started (and all betting finished) one cannot calculate what the final payout will be; whereas bookmakers can offer either SP or a "board price", that is, a guaranteed payout at a given price for a winning bet. (The SP for horse races is the average price offered by bookmakers when the race starts, as inspected by employees of the Jockey Club).
