i don't think it's optimal, but i haven't tested it so.. also the 6C connects earlier than you think it does, don't be afraid to alter the timing to be sooner than you usually do it. as for the 22C after that it's just a matter of having a good idea of 22C recovery, which will come in time
edit: actually wait that's the usual super missile combo, except for the 5C FADC shit which i don't even know is supposed to mean
edit edit: also this should've gone in the combo thread, not general
