So, we can now calculate the maximum number of consecutive losing bets that we are likely to encounter providing that we know the strike rate of the selection system.

Having calculated the maximum number of consecutive losing bets, what use is this?

We use it to calculate what percentage of our betting bank it would be reasonable to expose on a single bet.

For example, if we use a selection system with a strike rate of 75%, we are likely to encounter, at some point, a run of 5 consecutive losing bets. If we allocate 100%/5 = 20% of betting bank to every bet and we encounter 5 consecutive losing bets, our betting bank will be completely exhausted and we will not have sufficient funds to recover the losses. I therefore have a ‘rule of thumb’ which I use to determine what percentage of my bank to allocate to each bet.

Firstly, using the strike rate of the selection system, I determine what the longest losing run is that I am likely to encounter. I then divide the longest losing run into 20%. This is the percentage of my betting bank that I allocate to each bet. If I am using a backing system, then the percentage is applied to the stake. If I am using a laying system, then the percentage is applied to the liability of the bet. By using this method, when I encounter the maximum number of losing bets, 80% of my betting bank remains in tact. This is more than ample with which to recover the lost funds.

If we again use the above example of a selection system with a strike rate of 75%, then we are likely to encounter a maximum losing run of 5 bets. If we divide 20% by 5, the result is 4%. I therefore allocate 4% of my betting bank to each bet. Now, when my selection system encounters 5 losing bets in a row, I will only lose 5 x 4% = 20% of my betting bank and I will still be left with 80% of my betting bank. This is more than ample to recover the lost funds.
