I like the beer analogy better.

Take your days in gang stat. For simplicity assume that's how much back-up or protection you can have stored at one time.

Assume using the back-up / restore option adds 10 rounds of use.

If you are in your gang 0 days, one use puts you at 100%.
If you are in your gang 500 days, you will need to use the back-up / protection option multiple times to get to 100%.
