Right, well that's because you guys are both using pocket secondaries that neither of you play all that well (sorry it's pretty true, like, you're smart so you can get away with it, but neither of you were playing the characters well) so I guess what I want to know is: why did this come up in the first place? What makes you so sure ZSS doesn't beat King Dedede based on your pocket secondary matches against R's secondary and your games against Thiocyanide? lol at Thiocyanide btw.
I mean, ZSS isn't a top character, it's true, but none of your experiences or anecdotes really suggest that you have any idea how a good ZSS plays and that's really because there are only like two. Mr. R wasn't even frame trapping with dsmash, which is one of the big reasons Nick Riddle is so successful, he sort of made that mainstream and it's really good.
It's really easy to point out weaknesses in a character and say that these make them bad. People have been doing it with Snake for months but he's still winning. Saying things like, "we should be doing X to snake but no one does so he keeps winning" is just as bad as Peach or Marth mains who claim their character is good but their mains aren't doing certain things or whatever. Perception is reality and reality is everything, sorry. You have to actually be able to do these things to good players, you can't just say it's possible and shove ZSS in mid tier.
