either way, i beat the damage I got in that video just now too. I'll post video of it later but
5B, 214B, j.B, j.C, j.6C, land, j.C, land into:
100 meter, pure damage:
2C, 5C, j.C, j.6C, land, 3C (this catch is FUCKING HARD you have to keep them as low as possible throughout the rest of the combo), 214C - 3810 damage
a bit easier on yourself but a bit less damage is to do 5B instead of 2C here. The pickup from j.C into it is a touch harder since 5B is a bit slower than 2C, but they also juggle at an optimal position for the j.C, j.6C, land, 3C to hit. That variation does 3725 damage.
No meter, corner carry:
2B, 2C, 4B, (4),6B - 3185 damage
100 meter, corner carries from about the middle of the stage:
2B, 2C, 4B, 214B, 360C - 3687 damage
100 meter, corner carry:
2B, 5B, 5C, 3C, (4),6C - 3634 damage
Any of these can be chain shifted into at least 5B, 5C, 3C, 214C for a shitload of damage. I capped out at 4779 damage from the pure damage path into that.
EDIT: just found a better one for 100 meter and corner carry that does more damage than either of the pseudo-carries. The starter from above, into:
5B, 214B, 3C, (4),6C - 3691 damage
