I GM a lot of FATE 2.0, especially one-shots. A recurring problem for me is when a player takes two (or more) skills in the same area of differing specificity. The most recent example is a character who took Flying Jump Kick as a skill, as well as Offensive Martial Arts. This is less of a problem when the general skill is taken at the same or a lower rating than the specific skill (though it's still a problem), but in this case, as happens occasionally, the specific skill was higher than the general one.
I usually give players a bonus to skills' ratings if they are more specific than whatever default skill specificity is in a given campaign, the value of which is logarithmically proportionate to their specificity. The highest such bonus has ever been is +3, which was for the skill "Stabbing dinosaurs with a spear while hanging one-handed off of a cliff" (the rules on what skills are considered acceptable have since been redefined, but the general guidelines for specificity-to-bonus conversion have not). The one-shots I GM almost exclusively use 20 skill point PCs.
Currently, I add an effective +1-+2 bonus to general skills when they are used in an area the character also has a more specific skill in. I also add +1-+2 to any skill of rating 2 or better when it is used with another skill of rating 3 or better, favoring the larger bonus when both skills are of higher rating and when both skills are close in rating.
My issue with doing the same for specific skills is that the +1-+2 would be applied in literally all circumstances, since the specific skill is included in the general skill.
What is a good way of allowing general skills to help higher-rated specific ones?
