I'm pretty sure that would be counted as special proration.
Since it's over 100% for 2D, it just adds a little damage to the next move that it wouldn't usually have.
Also lets you combo for a little longer, since it helped to prevent your combo from deteriorating, proration-wise.
I need a crash course on modifiers, though.
I'm fuzzy on that stuff. I could be wrong.
Also, since I'm not a new mod, I don't think they will have one of those for me. lol.
:]
