Hey folks!
I'm putting together a league table for our Thursday night card games. I've managed to knock together a decent enough table but am having problems with our proposed scoring system.
Each player starts with a score of 100 and when two players play a game, the winner takes 10% of the losers score.
I just can't seem to wrap my head around it. Any help would be greatly appreciated!
I can provide a link to the table if you want to take a look at it for yourselves.

Many thanks!
