I found a bit of a loophole in your version of the Sun School feat:

A multiclass monk/swordsage with one level in monk can use shadow blink: swift action, grants a standard action, which you can flurry with. Then you use your move action for Shadow stride: another standard action. Lastly, you use your standard action to initiate shadow jump, and gain a third standard action.

If you're a Monk 11/SwordSage 9, you can flurry for 3 attacks as a standard action. That means that using this gets you 9 attacks at your highest BAB. With roundabout kick as one of your feats, that's 12 attacks. Or you could use two teleports and one full round action, for 13.

Was this intentional, or should it be fixed?
