I disagree with using Possessed against Grandmaster. The main reason is Possessed needs Overhead Slice to keep his best pressure strings safe, a true block string, help him build meter and enhance his mixups (42 and 421 xx to the fuzzyable high/low mixup or Teleport, for example). The problem for Possessed is Sub's Ex Slide punishes (Possessed) Overhead Slice on block. So Possessed can only pressure safely when he has meter to keep himself safe and when Possessed uses meter to stay safe that's less meter for his damaging combos considering his meterless damage is low. And considering Possessed is a more aggressive variation it wants to get close to Sub to do its damage and that's what Sub wants. Also consider that Sub's Ex Slide can punish Possessed regular Push at ranges that it can't when facing Balanced (this variation has the safest Push).
It also seems from your analysis that Teleflurry his meant to be a zoning tool for Balanced. It isn't in the current patch. That's what Push is for Balanced. Teleflurry is best used as a combo ender to allow Kenshi enough time to reposition himself, like staying full screen or advancing towards the opponent to pester with Push, among other things. Balanced's best position on screen is midrange, just like it was in MK9.
Also, Ex Raising Karma is meant enhances Kenshi's pressure game. For example, Kenshi's stand 1 recovers at 9 frames which means it's not perceptible if Kenshi does just stand 1 to throw or goes for the uninterruptible 111 xx to Raising Karma for full combo. If the opponent tries to tech a throw after the 1, they get full combo punished. If they block he first 1, go for a throw. Reading the opponent is key. Either way you'll get the opponent to full screen and you can zone a little, if you want. And if the guess right they guessed right, welcome to fighting games.
Balanced is best for the Grandmaster matchup.
