Variable Bet Profit (VBP)

Comparing results of different tipsters, it's not easy to assess which has achieved the best performance. Selections provided by the tipsters, who proof to Racing-Index, range from short priced favourite, to big priced outsiders, with all sorts of combinations in between.

When setting up a betting bank, to follow a tipsters selections, it's pretty likely you'd bet much smaller amounts if you were backing 50/1 outsiders, than if you were backing evens favourites. We therefore adopt this principle to rank tipsters within the comparison tables. This is done by calculating each tipsters profit, using variable stakes for each bet (the lower the odds the higher the stake). We call this basis, Variable Bet Profit (VBP).

VBP uses stake amounts of up to a maximum of 80 points. The table shows example rounded stakes for different odds.

The basis is the same for both backing and laying, but for back bets the stake is calculated using the horse's SP (used for both win and place bets, so that Each-way bets are treated the same as separate win and place bets), where as for lay bets Betfair SPs are used to determine the stake amount, with the Betfair place SP used for place only bets.

For both Back and Lay bets the profit for each bet will be based on the Betfair SP.

1/15 75
1/3 60
4/6 48
1/1 40
6/4 32
3/1 20
7/1 10
9/1 8
15/1 5
25/1 3.1
50/1 1.6
100/1 0.8

Example

Let's say a selection was returned at a SP of 7/1 and it's Betfair SP was 10.0 (9/1).

If the horse won the race:

  • For a back bet the VBP stake would be 10 points, which would produce a VBP of 90 points (10 x 9) minus commission
  • For a lay bet the VBP stake would be 8 points, which would produce a VBP of -72 points (8 x 9)

If the horse was beaten:

  • For a back bet the VBP would be -10 points
  • For a lay bet the VBP would be +8 points (minus commission)
