It’s hard to get it to work… I got some full reps, but nothing as close as consistant…
as Hol Horse said, the trickiest thing is to hit the cr.mk after the st.hp, but if you practice for some time you’ll get the hang of it. I’m using two karas for the moves now, and it works better, not to gain lots of distance(it’s only a little), but to prevent the early canceling. The bad thing is the input becomes trickier, because of the extra button:
after the first st.hp, kara the cr.mk with s.lk, so it won’t cancel early. I don’t know for sure, but Boss keeps forward motion the whole time, just down-forwarding for the cr.mk (and releasing for a brief moment for st.hp). Because of that, he may walk little bits between moves, helping with spacing (walking kara palm is dependant on this instant steps too)
the bad thing is if you can’t lead the opponent to the corner, you can repeat only 7~8 times the keeper jin’s route, before it misses. In corner, I did a maximum of 13 reps (without ender)
did some damage research as well, and the keeper jin has the nicest ground GJ combo damage (full, with finisher is cloes to 80 after 123), and you can do it on the corner too
oh, and no keeperjin will take the opponent to the corner if you’re past the middle background
the best one, I guess it would be this in corner, or going to it before the 5th hit (but it has no safety whatsoever):
-123xxGJ, [cr.mk, st.mp~st.hp] x 10, cr.mk, true kara palm (yes, it’s comboable!), hp lunge(GJ end), lp shoulder, f.hp, kara lunge (90 dmg on Ryu), or hp palm, hk upkicks (88 dmg)
the common ender is to stick a mp/hp shoulder after the st.hp that hits before a missed cr.mk, like in the video, and juggle accordingly
in corner, if by the 11~12th rep, you can cr.mk, f.hp(GJ end), lp shoulder, and the char specific ender (f.hp, lunge or cr.mk to upkicks, or just hp lunge/hk upkicks)
have to test with everyone, up now only tested with shotos, urien and hugo
it’s not very usable in matches, like most ground GJ, but has it’s karapalm-ish coolness and effect (more damage in exchange of hard ass training)
probably the beefiest damage would come from the cr.mk xx GJ one frame link
still have to confirm if this would work
cr.mk xx GJ, cr.lp, st.mp~st.hp, then to normal keeperjin reps (lk won’t work…it wont push enough the opponent)
