Similar to my old Cammy charts, I decided to do one for Yun too. To my surprise, he gets the same frame advantage as Cammy does on hit while having the benefit of being a lot easier to aim and harder to focus crumple, but he is a little less safe on block.
There are exactly 12 possible points you can hit on a standing Ken-sized enemy. The best you can do is a +11 on hit, and the worst is a 0 on hit, if you hit the very top of the head.
Numbers mean + on hit / + on block:
The first 8 points shown are entirely unpunishable (first 6 points for grapplers) and allow for combos on hit. The 9th point is the lowest possible divekick (LK and MK only) and is unsafe (-3 on block) but still lets you combo on hit (+3). Beyond that, the last 3 points are unsafe on block and don’t allow for combos on hit.
All divekicks are safe on hit.
Hitting at the waist level and below gives frame advantage, and as long as you aim at the waist or a bit below you should have enough leeway to not be punished in case they walk forward and block.
Also, this chart doubles for Yang too - just add +1 to the first number and +3 to the second number (Yang’s divekicks are almost always unpunishable on block).
