but how does this work with plus modifiers where A+ luck is effectively twice as much A luck. Effectively making it 100%?

Modifiers doubled stats? I'm fairly certain that in Fate, modifiers call for situational boosts, and are treated as a Rank-Up, and not an x2, in most cases. Then again, I'm not sure how modifiers are treated here.
