Belts/number of accrued wins connection
Someone else must have noticed this.
It appears that winning against a player that is a higher Belt than oneself counts for more wins.
How do I know this? I've noticed that when a player "Belts up", they're far more often - in my experience - to have just won against a player with a sizeable amount of experience. Coincidence? It seems far too common to me to be completely one.
Examples: I lost to a White Belt yesterday. He Belted up to Yellow.
I got my Green Belt accidentally beating Hamster at Judo.
