I decided to run an analysis on the existing martial arts styles in James' documentand see how to weight the various categories to minimize the difference between the "best" and "worst" art and minimize the standard deviation, then use that information to create a point buy system for new martial arts, as a supplement to the random system I proposed before.

My methodology was to take the bonuses and penalties for each martial art except for Mixed Martial Arts (which had no modifiers), sum the modifiers, then look at the mean, standard deviation, and the spread between minimum and maximum of the sums. Once I had done this, I started varying the weight of each maneuver with an eye towards minimizing the standard deviation and the spread.

To create a new martial art: Roll 2d6-7 and divide by 2 for the number of points available to spend. A martial art may have negative points and/or half points, with a range of -2.5 to 2.5 and an average of 0.


Points spent or refunded per plus or minus (maximum modifier +/- 3):
Punch: 2
Kick: 0.5
Headbutt: 0.5
Grapple: 0.5
Block: 0.5
Escape: 0.5
Diving Blow: 1.5
Throw: 1

With these weights, the mean is 0.25, standard deviation is 1.74, and spread is 5.5. All of the existing martial arts fit into the -2.5 to 2.5 range except for Sport Sambo and Sumo, both of which are at -3 and should possibly receive minor boosts.

The high-value martial arts are the two Kung Fus, Military Sambo, and Wrestling, all of which are at 2.5. Low-value martial arts are the previously mentioned Sport Sambo and Sumo at -3, along with Taekwondo and Judo at -2.
