Negative edging is no good for hitting 1 frame links I’m afraid GTF…sorry.
I’m sure I’ve mentioned it before but just for reference:
Frame 1 - Button is physically pressed (this will active Normals, Specials, Supers and Ultras)
Frame 2 - You release the button BUT even if you manage to release the button after only one frame, it is still seen by the system as remaining pressed on the second frame (this is why p-linking actually works. This frame will not activate ANY moves)
Frame 3 - The button registers as being released (This will activate Specials, Supers and Ultras but not Normals.)
So if you are trying to hit a 1 frame link, negative edging and double tapping are NOT as effective as p-linking as you still have only a 1 frame window in which to do your input.
Here is a summary of how to imagine it.
Imagine each letter to coincide with the press of a button. The first X being frame 1, then frame 2 etc etc. Thus I am demonstrating what the inputs would look like over 6 frames:
O = No moves will be activated
X = A move will be activated
P-linking:
X,X,O,O,O,O
Double tapping:
X,O,X,O,X,O,X
Negative edging: (Assuming you release within the 1 frame window)
X,O,X,O,O,O
I’m willing to be corrected on this, but I’m fairly certain I’m right.
So to sum up. If a move is a 1 frame link, you need to work on p-linking to improve your chances of hitting it. P-linking doubles your input window to 2 frames.
If a move is a 2 or more frame link, double tapping and negative edging are statistically more likely to help you hit it. P-linking will obviously also work too, but some prefer to use double tapping because they find it physically easier to perform and it gives you more “active” input frames in total, all of which are only 1 frame apart.
Hope this helps,
