As always these things are always easier to understand when following an example.
In this example 1 Point = £1 and Start Bank = £100. First stake = £1.
The bet wins. The debit is calculated as Previous Debit + 1 Point – Profit.
0 + 1 – 1 = 0
Rule 1 adds 1 Point to the stake. This would make the next stake £2. However Rule 2 means that the stake cannot be larger then the debit + 1 (0 + 1 = 1). So the next stake goes back to 1 Point or £1.
This time the bet loses. The new debit amount is calculated as before.
0 + 1 + 1 = £2
We then go through the rules again. Rule 1 increases the stake to £2. Rules 2 and 3 do not apply in this instance. The next stake is therefore £2.
The bet wins. The debit is calculated as before.
2 + 1 – 2 = £1
In TSM there are various staking plan settings you can edit. When Use Fixed Plus 1 Variable is unchecked the initial Stake is taken from the Percent % to bet setting. You can also link the initial stake to the cumulative total so that as the betting bank increases so does the value of 1 Point.
