Here's a few combos I came up with/got the unlisted damages for:
f3, 323, f23 xx sword flip= 30%: This one is an easier alternative to the f3 bnb submitted by karaokelove
f3, ji2, 323, f23 xx sword flip= 33%: This is a stronger f3 bnb than karaokelove's and the above combo. Might wanna highlight this as the new f3 bnb.
132, ji2, 323, f23 xx sword flip=33%: TONY-T's combo, this is the damage it does. You have it as a question mark (?).
ji1, 132, ji2, 323, f23 xx sword flip=35%: Same as above. This is how much this combo does.
132, ji2, 12, xx super=43%: Super combo off of 132. I recommend this one because it's faster than 323 (albeit weaker). It's actually the second fastest ground move DS has.
132, ji2, 32, xx super=43%: Almost the exact same combo as above, with the same damage. Use whatever feels better. 12 is faster, 32 has more range.
b1u2, f3, 32, xx super=41%: I recommend this one for its low starter. Weaker than 323, but more mixup potential.
ji1, b1u2, f3, 32, xx super=42%: Recommended for the overhead-low mixup.
ji2, b1u2, f3, 32, xx super=44%: Same as above, ji2 does more damage.
f3, ji2, 12=44%: Off a ground bounce. Since DS's ground bounce is an overhead, you can try to throw a jump move in for a double overhead mindgame.
f3, ji2, 32, xx super=44%: Same as above, similar to before, use whichever ground string feels more comfortable.
I don't know if you'd consider these "combos," but they're 3 hit air-to-air strings, useful for if you tag your opponent with any of DS's air moves. Optimally, you could follow up the air attack with a 323 combo, but these work in just about any situation. Very useful 3 hit strings for extra damage.
ji1, xx quick fire=10%
ji2, xx quick fire=12%
ji3, xx quick fire=16%
I also suggest you remove the yellow highlight from any combo ending with quick fire when it can end with sword flip since you're sacrificing damage for no reason at all. Also, I haven't tested the damage of meter combos since I'm having trouble getting the EX quick fire to connect all the bullets at the end of a combo (for now).
Pardon if some of these percentages are incorrect; I'm playing on an old non-HD TV and it's hard to read the text sometimes (although I'm pretty sure all of these percentages are correct). If someone wants to test these combos for accurate damage, be my guest.
I'd suggest you highlight ji3, 323, f23 xx sword flip as a bnb. DS's ji3 is really good and this is a nice combo to fit into it.
Finally, sorry if some of these have been mentioned already. I only read the original post.
Cheers.
