How about this:

[Hypermodder]

tournament-winner: +8p
2nd: +4p

each tournament-fighter: +1p

just to show that he/she(/it^^) took part in the tournament!

I think its kinda crappy, if you took part in around 10 tournaments for example, but alywas just get 4th or 5th or a lower rank.

Giving each tournament fighter +1 after a tournament (if he finished all his fights)
would be sensefull.

i mean, yo get experience in each tournament, so if you done 10 tournaments, you may be the same rank as s.o who just won 1 tournament and took part in 2 other tournaments.

Btw. I would make it like this:

1st: +8p
2nd: +5p
3rd: +3p
4th: +2p

lower: +1p
quitter: -3p
fighters who didn't fight: 0p
