SP and BSP in Greyhound Betting

What the SP Actually Means

Start price, or SP, is the snapshot of the market at race start. It’s the number you see on the tote board, the one that decides how much you get paid if you back a dog at the exact moment the gates open. In other words, the SP is the final price, no matter how wild the odds were a minute before.

BSP: The Benchmark You Need

Betfair’s starting price, BSP, is a whole different beast. It’s calculated from the whole pool of lay and back bets, not a single moment. Think of it as the average of every trader’s opinion, smoothed out by the exchange’s algorithm. If you’re looking for a fairer reflection of market sentiment, BSP is your go-to.

Why the Two Numbers Matter

Because they dictate your payout. Bet on a greyhound at SP and you get the official tote price; bet on the same dog at BSP and you receive the exchange’s averaged price. One can be dramatically higher than the other, especially in volatile races where a favorite gets scratched at the last second.

Spotting the Difference in Real Time

Here is the deal: the SP is static – it freezes the moment the race starts. The BSP is dynamic, shifting right up until the final second of betting. If you’re a quick-draw bettor, you might lock in a better SP before the market reacts. If you’re a patient strategist, you’ll let the BSP settle and capture the consensus value.

How to Use SP vs BSP for Edge

Look: the SP often overvalues the hot favorite because everyone piles onto the same dog. That’s a classic trap. The BSP, meanwhile, smooths out that herd mentality, giving you a more realistic price. When the BSP is lower than the SP, it signals that the market thinks the favorite is over-priced – a perfect cue to lay at the exchange.

Practical Example

Imagine a 5-to-1 SP for a mid-range runner, but the BSP ends up at 4-to-1. You’ve just discovered a 20% upside if you back at SP and lay at BSP. That’s the sweet spot where the exchange and the tote diverge.

Common Pitfalls

Don’t assume BSP always beats SP. In low-liquidity races, the BSP can be skewed by a few large bets, making it less reliable. Also, some tracks have a delayed SP release, causing you to miss the optimal window. Timing is everything.

Tools of the Trade

By the way, most betting software now shows both numbers side by side. Use that visual cue to decide whether you’re chasing value or chasing safety. If you’re on a tight budget, stick to the SP for consistency. If you’ve got bankroll to swing, chase the BSP for those hidden arbitrage opportunities.

Bottom Line

Here is why you should care: mastering the interplay between SP and BSP can turn a modest hobby into a profit-driven operation. One line, one decision – lock in the SP if you need certainty, chase the BSP if you crave edge. And here is why: the market’s inefficiencies are where the money lives.
