Ok, maybe a beer example will help you guys.
Each gang has a set amount of beer in the keg (protection) it can provide.
The longer you're in the gang your beer mug gets bigger ( the amount of protection you can receive).
A new gang member has a thimble for mug and an older member has a big beer mug.
And when the gang pours out a glass the new guy has a 100% full, meaning his thimble is smaller or equal to the amount of beer the gang has overall
Compared to the older guy who has 75%, meaning his mug is bigger than the amount of beer the gang has overall.

That help?
