I highly appreciate your findings,
@Take$$$ . It is beyond me, why you act so upfront, but whatever.
My opinion on 21 / 23 being the safer 50/50 remains unchanged. Yet it is no 'either/or'-thing. Whatever works...
Of course at the end of the day correct reads win matches. However I still think, that you should minimize the amount of opportunities for an opponent to get out of your pressure/vortex. Getting up fast or late is ONE way to get out of oki pressure, being able to guess the actual 50/50 right adds ANOTHER. - I think that "ji2, then 2" covers more options than e.g. a db2 by itself.
However I will definitly have to look into what your video shows. It is interesting how 2 deals with wake-ups. This is a general issue that you bring up (wakeups not being totally invulnerable ever). Dashing and pressing 2 might indeed be another great option, if it works as well as you claim it would. Especially because people might mash their wake-up by instinct (like I would have done) once they see you rushing in.
Good stuff. And congratulations on feeling vindicated too.

Besides I'd like to add another thing (and risk getting blown up by
@Take$$$ once again). It is possible to link a special to a whiffed (!) jump-attack. It has been like this ever since Mortal Kombat.
I have used this with Cyborg lately: You can jump backwards, press 2 or 3 immediatly (to cover follow-up jumps) and then shoot a projectile even after whiffing the normal.
However I think Canary might be able to make even better use of this. E.g. it is possible to do a neutral jump 2, then - on the way down - cancel into db2. This makes it kinda hard to punish said whiffed j2, because the opponent always risks getting hit by an aerial 50/50. - I wonder, if this can be used to cover even more oki-options.
