I think I never posted in these Seth forums, but I was just messing with him in practice mode a bit and found something interesting.
So, all of Seth’s Shoryukens (the first input) hit once if the opponent is hit, but will actually hit twice if the opponent blocked it. Then, I played around with it a bit and found an option select that will follow through on the two follow ups of the Shoryuken if you get a hit or FADC forward (or backward if you want) if the Shoryuken is blocked.
The input is:
:dp:+:hp:, (slight delay) :dp::r:+:mp:+:mk:, :r:+:hp:
If done correctly, the whole Shoryuken will come out and connect if it hits, or you will FADC forward after the two hits of the first part of the Shoryuken is blocked. It’s basically an option select automatic hit confirm.
If it is blocked and you FADC only after one of the hits from the first Shoryuken, you must delay it more, hence that note of “slight delay” I wrote up there.
There is one situation where you have to adjust a bit. And this is if your opponent charges up a focus attack. He will absorb the first hit, then get hit by the second, and you will FADC forward. But it’s no biggy; there is more than enough time to be able to react and get your head stomps.
And if the Shoryuken hits, continue pressure with this knockdown. Take a slight step back and then do a dive kick to hit in the front or jumping roundhouse to hit cross up.
Caution: There is one bigggg warning though. The second hit of the blocked Shoryuken can only be FADC’ed if you are very close. Like if you wanna test it out a bit, set the dummy to be a crouching Ryu with all guard. Go point blank to him and do a crouching jab and then do a Shoryuken and FADC the second hit. Now, go point blank again and do two crouching jabs and try the Shoryuken. That is the range where you can’t FADC the second hit.
So, only do this option select when you are very, veryyyyyy close to your opponent.

Ignore the triple dash; he just wanted to connect the EX tanden. You can easily distinguish the two situations of hit/blocked and react accordingly.
