Do the first 4b as late as possible (in the relaunch), the jb/c after that should be done not too late nor too early.
I don't have any problems with the first launch, it's the jb/c that I'm having trouble getting in.
Corner combo, 2c DELAY 5c, then 5abc, wait, then 5a 5b 2b 4b jb jc jb jc
Easier said than done, I can never get the 5b in for some reason. I guess I'm yet to get the timing down for the 5c.
Linking 236bx3 to 623c is easier on keyboard in my opinion, you just need to do the first 236b, then spam 26262626b and on the last 236b, do a 626C. (thats for keyboard, I've moved on to stick and I find it much harder to spam)
I can do 236bx3 easily but it's the 623c that's the pain. I can barely do that one outside of combos.
This is what I'm going to be working on for the moment:
Perfecting 2aac5cc jbc jbc airthrow and 2aac3b jbc jbc airthrow.
General blockstrings, I'm currently using 2abc 5c (I don't know why I'm using 5c, I'll try to force myself to use 214b/a).
Doing 623a/b/c reliably.
I think the corner and relaunch combos are out of my league for the moment. I'll try to come back to them once I get more confident with what I have.
