Or you can just do your plain old AA jump punch, smoke bomb, f4~EX bomb to eliminate all of those variables you have.
Or, you can just deep jik > d1~bomb, f4~EX bomb to again eliminate variables. That dash f4 stuff is a very slippery slope that is near impossible to consistently accomplish, especially when you have the "what-if" factor of when exactly that cujk hit, and how high of a launch you got. You can't react to that in timing your f4.
