The '+' modifiers are situational power ups under certain cirmcumstances. Its not a constant uptime.

For sake of argument, let's assume that a normal value is 1. In that case, E would be 10. And, every rank after that adds another 10, all the way up to A, which is 50. Now, things like B+ and A+ represent the unique ability to multiply these numerical values for just an instant. In other words, an ability ranked B+ would normally be weaker than an ability ranked A, but can momentarily exceed it by doubling its own power from 40 to 80. Heroic Spirits with A+ (plus) are rare, those with A++ (double plus) are extraordinary, and those with A+++ (triple plus) are in a class all their own."
