Bankroll Sharing system

[aufzuckerter]

Hi everybody,
We want to share our winnings in a group of 5 people, but there is a problem:

2 of us are better than the rest and are playing for more hours (for an hourly rate of approximatley 10$ and 5 hours a day)

The rest has an hour rate of 5$ and plays 2 hours a day.

What would be the perfekt sharing system to

a.) help the weaker players of our team
b.) reward playing many hours and making much profit
c.) minimise the risk of losing money at the end of the month compared to the previous

Thanks in advance

Andi
