Lightning legs partition property?

Is it just my imagination, or does this move have properties similar to charge partitioning with the input of kicks? It seems that I can do a dash and hit 2 kick buttons twice, and then dash again and buffer 3 more kick(x2) and a ex lightning legs will come out.

Sorry, I don’t know much about Chun.

you just have a long ass time to input it

do it while dashing, do it during another move, do it during a punch, whatever. just experiment with how long you have to do it and buffer the legs during whatever other motion you do

I see people walk and then LL out of nowhere.

How does it work? Rapid-fire moves have been broken down in other games (cvs2, st, etc) but what about 3rd strike?
