The idea behind the Lay 1-4 Staking Plan is that you increase the stake by 1 after a winner (losing lay) to a max of 4 until the deficit on that run is wiped out.

The Lay 1-4 Staking Plan is what I would call a gentle loss recovery staking plan. With this staking plan, you know what your largest stake is going to be before you start.

The best way to understand the lay 1-4 staking plan is by working through an example.

We will use a start bank of £100 and one unit will be £1.
The first bet is always one unit so the first stake is £1. Like with all examples, the bet loses.

As the bet loses we move up one unit and the next stake is therefore £2.
Again this bet loses.

The next stake is therefore 3. Our luck changes. We win.

The above result includes commission of 5% on any profits.
The series defecit is now -£13.05. The stake stays at £3 until the defecit is wiped.

You can see at bet 9 the stake reverts back to £1 as the series defecit is wiped.
A fairly simple staking plan that will consistently produce better profits than level stakes. The largest bet is always 4 units. In this example this limit is never reached. However if the losing sequence were to continue the maximum bet would be £4.
