They change the frame data on quite a few of her moves. For example, her 46P is neutral, whereas Tina's is +1 and Leon's +2.
Honoka's 3H+K is -4, whereas Hitomi's is -7, Mila's -8 and Tina's 6H+K is -9.
So they consciously modified these moves, and then thought a jab string should end with a tracking +1 mid kick on a character with 9/11/13 poke speeds.
