So most people have issues with this because of the strict timing involved. i will be the first to admit that timing the NJP in any of reptiles combos is probably the hardest challenge I've faced in this game -and i notice a lot of people having that issue. Unfortunatly there is no "easy" way to pick the timing up, however with a little practice with this method you should be able to nail it almost 100% of the time. First off, let it be known that all of the combos have almost the EXACT timing for the NJP so if you can nail one, using muscle memory you can nail them all. After days in practice mode, i've found this method to work the best. after you initiate the combo, hold up, try to time hitting 2 to be the exact moment you go to leave the ground rather than when you are already in the air. in other words, you are hitting 2 before the first frame of leaving the ground. If done correctly you will land the NJP 100% of the time. The hardest part of this is not hiiting 2 too soon. if you do, you simply do a high punch. i know some people say hit 3 or 4 frames into the air, however this works for me, and i had trouble before i started timing it this way so i hope it helps you also!!!
