I like this.
U could use a command in-game in your server like:
/ set wpt ( win point treshold ) 75000 ( or any other number between 25000 and 3000000 so it can't be abused )
And also
/ set wpt 1 for on and 0 for off

I remember some gm event where you had to win with a 50k points difference from opponents score, to make a valid point in the event. It was the blind date event i think.
