Oh, are you talking about the maneuvers? That goes to your default.

How do I learn maneuvers?
Maneuvers are bought from a default since they are based on a default skill. As such, there is no real necessity for any character to purchase maneuvers since he will have learned the basic maneuver as part of his prerequisite training. However, they are available for characters desiring to master certain maneuvers within the skill.
Basically, the "default" is listed. That's your ability without learning the "maneuver." However, the specific maneuver can be increased with practice, so you spend points to increase it. Usually its maximum value cannot exceed the value of the prerequisite forming the default.
So if it defaults to Judo -4, then that's the value with you never learning the maneuver.
But if it's a "hard" maneuver and you spend 6 points on it, then that specialized maneuver would be the same as performing general judo on the target. It sort of takes away the modifier for using a difficult maneuver subskill within the general category of "Judo."
