623 hp doesn’t work which I have just tested extensively @KungFoo
It works if you end the dragon punch in forward though
The shortcut system seems to work this way: You need 4 inputs for a CA which are :d: :f: :d: :f: in that exact order.
In order to find the shortest route to the desired CA cancel, you just have to add the inputs that are missing somewhere in this sequence.
:d: :hp: :f: :d: :df: :hp: :f: :hp: to be the most input efficient cr.HP xx HP SRK xx CA
I’d like to ask @Eternal how the shortcut system works in detail though or if someone of you has a link or knows a sticky where I can read up the exact mechanics of this confusing-ass system.
Here’s a screenshot for the 4 inputs CA:
Here the shortest route in action (ignore the first forward input, that’s me walking up to the dummy and the punch on forward is me mashing):
I couldn’t get to input :f: :d: :hp: :df: :hp: :d: :df: :f: :hp:cleanly without sliding over :f: on end of the srk motion in a speed where it should work.
But based on what I found about the input shortcut system so far, it seems like :df: inputs block CA’s completely unless you slide over to :f: shortly after :df: :hp: in which case the uppercut gets “eaten” and replaced by a CA, which happens often to me when I practice :d: :lk: :d: :lp: :dp: :hp: hit confirms.
