Production and Recovery is a two-layered strategy which many people use, even without realizing.

In the most purist mindset:

   
• The production layer is the one making the units.
• The recovery layer is the one that kicks-in when the production layer misses and its aim is to "patch" the balance to break even point.

This P&R combo can take many different forms, including combining VERY DIFFERENT approaches, that complement each other in the overall strategy.

Take for instance the combination:

Production: Last 5 lines.
Recovery: 36-unit parachute.

Last 5 lines is a flat bet covering 30 numbers with 5 chips. You can expect long sets of concatenated wins when the further-behind becomes a sleeper. It has a tendency to do that already.

The 36-unit parachute is a progression in risk. It has varied payout; at some levels netting more than +5.

If you may, a standard progression is also a P&R combo:

- First step of progression = Production. A hit on it nets/makes the units.

- All other steps = Recovery. The goal being to bring the balance back to even after missing production/first step.

There are many other combinations or schemes for Production and Recovey combos.

In this thread we can see several of them; perhaps one of them suits you.
