Yeah in most 3D's its universal you tap 33. The reason behind this is because usually it takes too long to hold 2 and wait for the duck to come out. I don't have a number for each game, but the average duck takes 5 frames in 3D's, but if you tap 33 fast enough a quick duck will come out. Although ever since the 1.03A came out. You can duck high's in one frame.

I don't think that 1 frame duck applies to grabs though, so there's still a use for the proper way of fuzzy guarding.

pressing 33 is going into crouch state and then canceling the crouch state into a crouch dash. That's why it's 1 frame. Pressing H or F after it will pop you back up into standing while remaining practically stationary.

I just knew that worked I never really put thought into how it works. That is awesome I'm still learning new stuff.

Obviously doing 33H has issues with characters who have parries.
