(Standard) UpB sweetspot

[FlamingForce]

So after some uair-strings practice I've noticed that sometimes my UpB finisher kills and sometimes it doesn't and the difference in how close someone gets to dying is decently significant. (In both normal games and training mode)
Does the upB have a certain sweetspot on the 2nd hit? And if so, how do you land it consistently?

No sweetspot. Up b OOS is the most consistent way to land your up b. the aerial version is weaker then the grounded one.

Yep, no sweet spot on the 2nd hit.
