how do you pull off jeans 46p+k kppkpk k

i can do it up to kppkpk but i cant do the last k ( the knee to the face ) is there any trick to it
also i need help with 43646 i can only go up to 6 i know the problem for this one though i have failed at it so many times when i get to 6 my fingers reset to 43

 

You just have to time the last kick to when the last P hits. IIRC it's a 3 frame window.

For the 43P+K one, you answered it yourself.
