I love being a Pikachu Board Member....
I love being a resident scientist for the Pika's
I love discovering 2 and improvising 3 other thunder AT's for pika.
I love having connections with K-prime.
I have some ledge frames for Pikachu. Right when he grabs the ledge he has 34 frames of invincibility and can let go on frame 14. I don't know if it's the same for every character, but I hope that helps.
Edit: Okay, I just tested this with every character and coincidentally Pikachu has the least ledge grab lag and everyone else has the same. Tethers also have less ledge grab lag. These are all just normal ledge grabs. I did not test with up b, but it doesn't seem to make a difference.
Pikachu
Invincibility Frames - 34
Ledge Grab Lag Frames - 12
Ledge Drop Frame - 14
Everyone else
Invincibility Frames - 46
Ledge Grab Lag Frames - 24
Ledge Drop Frame - 26
Tethers
Invincibility Frames - 23
Ledge Grab Lag Frames - 1
Ledge Drop Frame - 3
Extra Info
-You can only re-grab the ledge after 30 frames from letting go. For tethers it's like 1 frame.
-You cannot buffer a ledge drop. So you have to be frame perfect on the ledge drop if you want to take advantage of every invincibility frame.
-Invincibility frames start as soon as the character does their ledge reach animation. For tether users, they start when their tether is fully retracted.
-The maximum amount of invincibility frames on ledge drop is 21 frames for everyone.

So....
TOON LINK
When he hugs he's got:
46 invincible frames
- 26 lag frames from grabbing ledge =
~21 invincibility frames left after letting go of ledge
(
1 FRAME that the ledge is un-occupied because tethers can only claim ledge again after 1 frame from letting go)
So...
35 frames invincible initial hogging--->
DROP (still invincible): 1 frame free ledge--->Re-tether: 12 more hogging frames (invincible)--->
DROP (still invincible): 1 frame free ledge--->Re-tether: 12 more hogging frames (invincible)--->
DROP (still invincible): 1 frame free ledge--->Re-tether: 12 more hogging frames (invincible)
= 71 frames of ledge being occupied with only three 1-frame chances for Marth/Mario to claim ledge (2 actually since by the time the 3rd chance rolls around, Mario and Marth are too low to sweetspot anymore...).
^For the example above, I trimmed each hogging duration by a full 10 frames each--what that means is that a total of '71' hogging frames can be acheived if the TL is NOT perfect.
If the TL re-tether's PERFECTLY its a whopping 111 frames of invincible edgehogging with only two 1-frame windows for sweetspotting at ANY one point in time!
Lets look at Marth.
If TL hugs at the same time as marth side-b's, then TL's 46 invincibile hogging frames will outlast side-b (30 frames) and an immediate dolphin hitbox (11 frames). Marth can delay his up-b by 5 frames and TL's invincibility will still outlast Marths up-b. If Toon Link re-tethers at the end of side-b, Marth could delay up-b by 10 frames and TL's invincibility will still outlast dolphin.
What if TL's timing is off... what if TL doen't grab the ledge at the SAME time as Marth's Side-B?!
ANSWER: TL only lags for 26 + 1 free ledge frames before he can retether.... IF TL hugs ledge @ the same time as marth side-b's, TL can barely refresh hogging frames (BEFORE MARTH's Side-B CAN EVEN FINISH) and secure edge for another full 21 frames with a window for error of ~3 frames (can re-tether anytime between frame 28-30 of side-b's duration)!
If Toon Link performs the initial hug earlier, then TL can ALWAYS easily re-tether before marth's side-b finishes (and has a good window to time re-tether towards the end of marth side-b). Since marth's dolphin hitbox lasts from frames 5-11, If TL's re-tether is done between frames 21-30 of side-b (30 frames total), TL's invincibility will outlast an immediate up-b by 1-10 frames! If the re-tether is done on frame 25, even if marth delay's the up-b by 5 frames after side-b, TL's invincibility will out last up-b. If the re-tether is done right at the 'finish' of side-b (frame 30), even if marth delays the dolphin 10 frames after side-b finishes, TL will still be invincible.
What if Marth delays up-b:
Since dolphin's hitbox starts at frame 5 and can hurt OoS at point blank its safe to assume that at frame 5, marth is at the bottom of his ascension (cannot sweetspot just yet on frame 5 of dolphin). TL has 3 tether-grablag-frames and 1 free ledge frame = 4 frames total required to re-tether. The re-tether is faster than dolphin sweetspotting the ledge, and TL is still invincible for the entirety of the re-tether which means:
All Toon Link has to do is (1)hug the ledge, (2)watches for side-b, (3)re-tethers near the finish of side-b, and (4)re-tethers again slightly before or at the moment marth begins the dolphin slice, and it is IMPOSSIBLE for Marth to hit Toon Link or sweetspot the ledge during ANY part of TL's edgehogging.
Now for Mario....

As stated above, all toon link has to do is sweetspot the ledge slightly before mario capes or at the same time mario performs side-b to be
able to re-tether before the cape finishes. Then TL just times the re-tether towards the end of the cape animation, but this time does not have to worry about Mario delaying the up-b after the side-b (cause mario will already be too low if he did indeed delay his up-b enough). So toon link just re-tethers at the end of the cape animation (mario would have to delay his up-b more than 7 frames after the cape animation finishes before TL's invincibility wears off[21 ledge invincibility frames > 14 frames of Mario's up-b hitbox]) and the gimp is done.
If done right, it is also impossible for mario to sweetspot the ledge.
As I was emphasizing before, the MAIN factor in these 2 ever becoming 'vulnerable' is the fact of whether they can land ON TOP OF the stage and not whether they CAN STALL to survive. TL's invincibility far outlasts all of the stalling moves AND both up-b's. Furthermore, the only one to two 1-frame unoccupied-ledge chances for mario and marth to sweetspot (when TL detatches for a re-tether) almost occur when they can't even up-b yet.
So even now, I am still looking for replays of marth's and mario's landing ON the stage. Then i'll be happy to place them in 'vulnerable.'
