Hey sorry for the late reply:

1. As far as i know power is calculated the same on all platforms (swing speed of controller), i dont think that would change. See Comments of https://www.reddit.com/r/ThrillOfTheFight/comments/tat0es/how_do_kos_work_exactly/ Damage is calculated as following: SpeedOfSwing (capped at 3600) * Multipliers (like Weakspots Bonus, Trauma etc.) - i think that you might not hit the weakspots the same as before, maybe because of a different grip on the controller.
2. I think the platforms are compareable, with the exception of loadingtimes being faster on PC vs Standalone.
3. You have a point with the multiplier. Maybe i'll add free multiplier for every difficulty. Cheers

Edit: No Verification for all difficuties added. No need to show settings basically free multiplier settings.
