Personally Shock, I wouldn't rate it that high. It's not THAT difficult as long as as you're in your corner and you can jump over them and into the corner.
How many times on average does it take you to get the positioning right and how often do you not even get the chance to do it because only one jab can be done when you are too close?
Well I can get it pretty often. The only thing is when I gun them into the corner and then do deep JK aalp, I always do the gun too soon and it doesn't come out.
