Not trying to crush your dreams, but we're not really relevant in a continent that already struggles to be relevant, i know how it feels to go to tournaments & all, but in your case, it's not that big of a deal, still, good luck for Top 64.
Anyway, let's get to the fun part: matchups.
The biggest issue i have with your rating of some matchups is that you seem to either ignore neutral or your idea of X Character's neutral is kind of flawed. The Cloud matchup is the biggest example of this:
- Cloud's neutral b never played a big part of his neutral, it is a mixup at the very best
- Courtesy of the multiple ways of cancelling Limit into basically anything, good Cloud players won't have much trouble charging Limit bit by bit, even against the fastest of rushdown characters. And i'm not taking into account Stage dependant limit charge ( Charging Limit on Duck Hunt's Tree & Smashville's platforms are the biggest case of that ).
- While Cloud's disadvantage state isn't good for sure, Roy's isn't good at all either, and you'll likely get as exploited by the likes of UpAir juggles, reverse Nair edgeguards & most combos in Cloud's arsenal given that Roy is among the biggest combo fodder in the entire cast once he gets you to this state, which brings me to the point of Neutral Game.
- Cloud's overall much stronger autocancels, frame data & safety may allow him to strike before Roy does, and this is a key part of the matchup: Their tools in neutral will play an important part, and as i just mentionned, Cloud's neutral tools are unarguably stronger than Roy's, ultimately leading into him getting the edge over Roy more often.
While i'm not a Roy specialist by any means, i'd probably say this matchup is closer to 6/4, but i may be wrong, i'm just sharing my own thoughts because it didn't feel right to me.
