I was playing some 3S last weekend. It was a good time and overall I thought I did ok. Here are some replays. There are always execution mistakes and simple slow reaction stuff, but overlooking those things I think I adapted well to what my oponents were doing defensively and sometimes offensively. I remember waiting for Akuma's divekick and punching it down with Urien's S.HP. Also, even though I've never practiced it I was doing back fierce into Hyakuretsu with Chun consistently. I just palm mashed the buttons violently and it didn't let me down. When I got home I decided to have a look at the specifics of Hyakuretsu to see if I could improve my input or apply it elsewhere in my rudamentary Chun style.

As I allready knew, you need to press the same kick button 5 times to get Hyakuretsu. That emans palm mashing is like using a hammer to thread a needle, but not quite. For whatever reason using that way of mashing is actually very reliable. Though pressing b+HP+MK,MK,MK etc. is not incredibly hard, I often fail getting it before the cancelable window ends. So for the time being I'll stick to the hammer until I can speed up my button presses. What I also found out (using my frame counting method in one of my oldest entries) is that you have appoximately 50 frames to finish your Hyakuretsu input. That means an average of 1/6th of a second per kick. This number is not exact, because I don't have any way of controlling input as precise as a programmable pad. My slowest Hyakuretsu was 48 frames between first and last button press.

You can buffer your kicks during anything including a dash, UOH, normals, air reel and getting up. If you're good at double tapping you can do things like: double tap MK during a dash then hold down and press MK 3 more times to do C.MK x MK.Hyakuretsu.

The testing I did suggests you can't kara cancel the same kick you're using to do Hyakuretsu into the actual special. So if you press LK 3 times and then from idle state double tap LK you'll only get the LK and not LK kara canceled into LK.Hyakuretsu. You CAN, however, kara cancel any other normal. So, if you do LK x3 followed by MK~LK you'll kara cancel the MK into LK.Hyakuretsu giving you some more range on it. I actually don't know what happens to the Hyakuretsu input if you've pressed all 5 kicks on time but because of the kara cancel rule you didn't get the special. I haven't done testing on this yet, and I'll try to do it later.

Oh, and in case anyone didn't know: EX Hyakuretsu is done simply by pressing 2 or more kick buttons buttons as the last input of the Hyakuretsu. If you finish the first 4 button presses quickly you can walk forward a bit before pressing the final button. I'm not sure if this is the exact method for the infamous walk up Hyakuretsu, because if you do it this way the distance you're allowed to walk is quite small really. At least, it is with MY input speed. So maybe it has something to do with the 5-button-presses-but-no-special thing I mentioned in the previous paragraph. I guess I'll find out sooner or later. Look at a little demo of everything I just wrote here.
