Back Single Step Recovery

The Back Single Step Recovery staking plan tries to recover all the losses in one step. Every betting sequence starts with a base stake equal to a fixed percent of the bank. The percent value can be applied to initial, current or highest bank.

After each race the cumulative profit of the betting sequence is calculated. If the value is:

1.1. Positive

The staking plan moves to a new betting sequence.

1.2. Negative

The staking plan tries to recover the entire sequence deficit in the next race. The employed algorithm depends on the number of qualified selections.

1.2.1. Single selection qualifies

totalStake = baseStake + sequenceLoss / (selectionPrice – 1)

where:

  • sequenceLoss = total sequence deficit.
  • selectionPrice = selection decimal odds.
  • baseStake = base stake equal to a fixed percent of the bank.
  • totalStake = stake to place for qualified selection.

1.2.2. Multiple selections qualify

The following steps are performed:

Step 1 – The race profit is calculated, assuming that one of the bets wins and the total stake placed for all qualified selections is equal to the base stake:

baseStakeProfit = |(100 / totalProbability) – 1| × baseStake

where:

  • baseStake = base stake equal to a fixed percent of the bank.
  • totalProbability = total probability of winning for all qualified selections.
  • baseStakeProfit = profit earned in case any of the qualified selections bets wins.

Step 2 – The race target profit is calculated, which includes the sequence deficit:

targetProfit = baseStakeProfit + sequenceLoss

where:

  • sequenceLoss = total sequence deficit.
  • baseStakeProfit = profit earned in case any of the qualified selections bets wins, when total stake placed for the race is equal to the base stake.
  • targetProfit = target profit for the race.

Step 3 – The total stake placed for all qualified selections is determined using the following formula:

totalStake = (1 / |(100 / totalProbability) – 1|) × targetProfit

where:

  • totalStake = total stake to place for all qualified selections.
  • totalProbability = total probability of winning for all qualified selections.
  • targetProfit = target profit for the race.

Step 4 – The dutching algorithm is applied in order to split the total stake between the qualified selections.

In case the total probability of winning for all qualified selections exceeds 100%, the race profit will be negative.

In order to limit the losses in case of long losing runs, a maximum value for the total stake can be set.

Settings

The following parameters can be configured in this staking plan:

FlashRace - Back Single Step Recovery staking plan settings
Back Single Step Recovery staking plan settings
  • Percent of X bank to bet: the value of the base stake expressed as percent of the bank.
    • X: the type of bank to which the percent value is applied:
      • initial: the percent value is applied to initial bank.
      • current: the percent value is applied to current bank.
      • highest: the percent value is applied to highest bank.
  • Stake must not exceed X% of current bank: the maximum value allowed for the total stake in a race, expressed as percent of current bank.
  • While not in recovery, use dutching to calculate stake when multiple selections qualify: this option applies dutching algorithm to split the total stake among multiple selections in a race. When the option is not used the total stake is placed for each qualified selection. This setting applies only when the betting sequence does not have a negative cumulative profit.

Back Single Step Recovery Example

Let’s assume the following settings:

  • Initial bank: £200
  • Percent of current bank to bet: 2
  • Stake must not exceed 100% of current bank
  • While not in recovery, use dutching to calculate stake when multiple selections qualify: not checked

Step 1

  • base stake is £4
  • 1 selection qualifies at decimal odds of 4
  • total stake is £4
  • bet losses and the loss is £4
  • sequence cumulative profit is -£4
  • current bank is £196

Step 2

  • base stake is £3.92
  • 1 selection qualifies at decimal odds of 5
  • total stake is £4.92
  • bet losses and the loss is £4.92
  • sequence cumulative profit is -£8.92
  • current bank is £191.08

Step 3

  • base stake is £3.82
  • 1 selection qualifies at decimal odds of 4
  • total stake is £6.79
  • bet wins and the profit is £20.37
  • sequence cumulative profit is £11.45
  • current bank is £211.45

Step 4

  • base stake is £4.23
  • 1 selection qualifies at decimal odds of 3
  • total stake is £4.23
  • bet wins and the profit is £8.46
  • sequence cumulative profit is £8.46
  • current bank is £219.91

Step 5

  • base stake is £4.40
  • 1 selection qualifies at decimal odds of 4
  • total stake is £4.40
  • bet wins and the profit is £13.20
  • sequence cumulative profit is £13.20
  • current bank is £233.11
