I am going to make a video of this. Basically, uhmm... ok i need to do bullet points to explain this because its all messed up in my head. Vids comming soon, i have tons of pichu footage. PS if anybody wants i could upload a few pichu friendlies..
When you upB against a wall, angled into the wall, the distance is shortened massively.
So lets say you are off stage, and use the first part of upB to hug FoD's wall.
You have to get used to the distance of the 2nd part of upB.
When you know the distance, use upB to get to the part of the wall just below the edge.
Now do the 2nd part of upB upwards and angled towards the wall slightly.
Congratulations, you just sweetspotted the edge.
Limitations:
you will almost certainly SD 70% of the time.. this technique is broken and doesn't seem to function the same way every time.
