Question about fox double jab combo: how do you know if it works or not in training mode? Does it make real combo (like 6-8-12 hits in training, or just 1-2;1-2;1-2 hits?)
For exemple, you can do it at any % vs Bowser Jr, how many hit do you get in training for those who knows how to perform double jab combo plz?
The combo counter won't register this as a real combo, since it only takes hitstun in consideration. The reason this works is because of hitstun from the jabs
and landing lag from being popped up by Fox's jabs.
The best way to know if it works is to get a training partner to help you out. Go in training mode and initiate the combo. Have your partner try to break out of it by 1) shielding when he/she lands, 2) trying to jab when they land. If they can't, you've got the timing right. Keep in mind the character they're using too, make sure to read the description.
If you don't have a training partner, you can still practice by counting frames. Try doing it in slow motion first. Remember you need 20 frames in between the jab 2 -> jab 1.
At 1/4, 20 frames is a little bit over a second. At 1/2 speed, 20 frames is just a bit over half-a-second.
