Yun vs Chun-Li: Whiff punishing Chun-Li's standing HP

When whiff punishing Chun-Li's HP, these are the 3 main ways to do it

    - LP Lunge Punch

    - Crouching MK

    - Crouching MP

I will go into the Pros & Cons of each one, then explain how many frames you have to react with the button press at each distance

LP Lunge Punch  

        

    Pros: 

1. It has the longest reach out of the 3, positioning is lenient
2. Causes knockdown
3. Builds 17 points of meter

    Cons:

1. It requires a quarter circle motion, so it takes more frames to react with it compared to just pressing a button, unless the QCF is buffered ahead of time

    Distance:

1. Distance of 257~254 pixels: 13 frames reaction
2. Distance of 253~250 pixels: 14 frames reaction
3. Distance of 249~246 pixels: 15 frames reaction
4. Distance of 245~242 pixels: 16 frames reaction
5. Distance of 241~218 pixels: 17 frames reaction
6. Distance of 217~214 pixels: 18 frames reaction
7. Distance of 213~180 pixels: 19 frames reaction
8. Distance of 179~176 pixels: 20 frames reaction
9. Distance of 175~172 pixels: 21 frames reaction
10. Distance of 171~155 pixels: 22 frames reaction
11. Distance of 154~153 pixels: 23 frames reaction

    The distance is lenient, but the more distance between the characters, the more difficult it becomes

    

    Even the distance where it's reasonable is lenient too

Crouching MK

        

    Pros:

1. It's easy to execute (you only need to press the button)
2. With Lunge Punch, you gain 26 points of meter
3. Knockdown
4. You can combo into Lunge Punch from the very max whiff punish distance

    Cons: 

1. The distance is stricter than the other two

    Distance:

1. Distance of 179~178 pixels: 15 frames reaction
2. Distance of 177~165 pixels: 18 frames reaction
3. Distance of 164~153 pixels: 20 frames reaction  

Crouching MP

        

    Pros:

1. It's easy to execute (you only need to press the button)
2. With Lunge Punch, you gain 26 points of meter
3. Knockdown
4. You can whiff punish from farther away than crouching MK

    Cons: 

1. Although it can whiff punish from farther than crouching MK, the distance where it can combo into Lunge Punch is smaller
2. EX Shoulder is often not worth it due to the meter cost, but it can be useful if it kills

    Distance:

1. Distance of 187~182 pixels: 14 frames reaction
2. Distance of 181~174 pixels: 17 frames reaction
3. Distance of 173~153 pixels: 20 frames reaction

Final thoughts:

        

Crouching MK will be easier to use than Crouching MP due to Lunge Punch connecting at all distances

If looking to whiff punish from more far away, just react with LP Lunge Punch

Save Crouching MP mainly for when "Crouching MP > EX Shoulder" will kill
