what makes the gap?

[pyro93]

What makes the gap the weapon mastery or the force mastery?

[EllisD]

Your character level Minus your highest mastery level (weapon or force tree, whatever is highest).

[PrincessBoA]

It doesn't matter, the highest masteries level - your current character level will give you some gaps

For example,
Your Level: 65
Your Masteries: Fire 60, Lightning 55, Heuksal 50
Your Gaps: 5

Fire is the highest level masteries. So, 65 - 60 = 5
