weakknee

Been labbing how Falcon can escape dthrow weak knee gimp at the ledge.

Okay so there's two ways he can do the weak knee:
1. SH delayed knee /w no fastfall
2. SH instant knee /w fastfall

Both of these hit double jump sweetspot, so let's explore alternative options.

Let's start with instant uair. Even at 0% if the Falcon does an instant SH knee then it will trade (so ask whether the trade will be favourable or not).
You may be able to outrange the knee with uair, but I was not able to get this in frame advance.
However, let's say they delay the knee so they don't have to fastfall.
At low% your instant uair will hit him in the startup frames of this delayed knee, so it wins. However at higher% it will trade with or lose to the knee (unless you can somehow outrange it like I explained earlier).
If the other Falcon knows you're going to instant uair they can just utilt you (which you can adapt to by DJ sweetspotting), but this is about option coverage.

So there's another option that I tested which was DJ back/inplace airdodge diagonally up into stage/ledge.
This one's weird for the instant knee /w fastfall.
On every stage other than BF, Falcon can DJ walljump after the knee. This beats the airdodge at higher % as you can simply DJ walljump uair afterwards to hit them after the airdodge. However at lower % they can get ledge from the airdodge before you can uair them if done correctly.
So this option beats the instant knee on BF, beats it at low% on other stages but loses to it at higher% if they know to walljump uair.
Also, if they utilted to cover instant uair, they could uair you after the utilt in your airdodge lag... sooo... option coverage.
This option directly loses to the delayed knee since they can just DJ uair after the knee to hit you in your airdodge lag. Though, at low% you could DI the uair to get ledge, so still interesting.

Took me a lot of testing, hope this was useful. If anyone has any ideas then throw them at me.
