Hello everyone, been awhile since I've actually posted in here.
I am presenting some viable data for situations involving trades via jab. This shows how much positive frame advantage Ayane is actually at after she has traded jabs with an i9 or i10 frame jab opponent.
Before I have mentioned that Ayane's jab is very unique compared to any other character in the game. When she jabs while facing forward, only a hitbox extends forward while her hurtbox actually shifts back a bit. So when she's jabbing, she is likely to hit something the opponent sticks out with proper spacing, instead of her getting hit by something. This is a very good and unique property she has because it literally means that if she trades jab with another character, they have no high or mid neutral strike to challenge her if she jabs again after the jab trade (she will always win the challenge).
The overall counter hit advantage Ayane gains off jab is +3. However in a situation of a trade, it'll vary, but she will always win after the trade with another jab no matter what if the opponent decides to challenge with a high or mid neutral strike. The variance is going to be displayed so you will learn to know what your other options actually could be outside of another jab after a trade.
The following is to be treated under the assumption that you've clashed/traded jabs with the opponent character. The list displays how much frame advantage Ayane will always gain after a trade.
Against an i10 frame jab character:
vs Ayane: +0 - In the mirror match, this situation does not apply since you are using the same character with this unique property.
vs Akira: +2
vs Ein: +1
vs Eliot: +3
vs Genfu: +3
vs Hayabusa: +3
vs Hayate: +2
vs Hitomi: +1
vs Jacky: +3
vs Jannlee: +3
vs Kokoro: +1
vs Leifang: +1
vs Marie Rose: +2
vs Mila: +3
vs: Momiji: +1
vs Rig: +2
vs Sarah: +4
vs Zack: +3
Against an i9 frame jab character. This is when you've gained a +1 advantage from something such as BT6K at range or 66KK4 on block. However against Kasumi and Phase 4, if they block your BT6K even up close for +0, their jab with clash/trade with Ayane's anyway.
vs Alpha 152: +2
vs Christie: +2
vs Honoka: +1
vs Kasumi: +3
vs Pai: +3
vs Phase 4: +3
How I got the data:
Setting the training dummy's Com Reaction to Strike - High Punch. Hitting the dummy with 2P on neutral then jab so we'll trade. Another way was to set the training dummy's Com Action to Guard All and Com Reaction to Strike - High Punch. Do BT6K on block then jab so we'll trade. I'd repeat the process against myself as well with having Ayane as the training dummy.
Another thing I did was use a character that has a +0 on block move, then trade jabs afterward. Same result.
Point is, a basic trade like this favors Ayane no matter what.
