There's a good example.

Was playing All-Star with Lucas. Got to Marth/Ike. I didn't heal before the match at 50%. They knocked me off the edge downward, then jumped above me. So I had to angle my PK Thunder recovery almost exactly vertical. And it didn't work. I was off by a few degrees. I hit the underside of that left side ledge and bounced downward.
