If you need a bit of a visual cue for the dash links:
Dashing from throw: When Mu turns her face back to the side
Dashing from Sword of Decimation: After Mu puts the sword away
Dashing from 214D whiff: When the circle underneath Mu disappears
Dashing 2B: When Mu lands on the ground
If you want to try a more lenient throw combo that sacrifices some damage for better oki:
Throw, dash 5B, 6A, JC j2C, dash 2B, 5C, 6C, oki/SoD/632146C
