I could've sworn that moves only lost knockback when you actually did damage with them, not when you hit a shield or whiff. Did something change between last week and now?
I think u're right about that according to the post made by the finder, but i noticed something in the video.

He uses the fair a total of 8 times before he sweetspots it (the ninth time) and he uses multiple attacks in between.
He uses the fair 3 times (hitting it all 3) the next attack he lands is an f-smash, misses a fair, lands an f-smash, forward b, forward b, reflects an arrow, reflects another arrow, then hits with the fair again, f-smash, then a fair, and then he hits with the last (sweetspotted fair).
Missed attacks supposedly do not recharge and also supposedly don't decrease fairs so considering this, he missed 3 of his fairs so he hit with the fair 5 times before sweetspotting it the 6th time. He does 5 attacks that hit (meaning it should have recharged significantly but not sure how much), then he does it another time (diminishing), then f-smashes (recharge), then he lands a fair, and then he sweetspots a fair.
To me it did not seem that after doing those several attacks in between it should have diminished that significantly. It really depends on the numbers i guess.
the % that the attack diminishes might resemble some kind of pattern to how powerful it is. the first 2 times it does 4% (but the 2nd time should have had less kb regardless), then the 3rd time it does 3%. After having done several moves that should recharge, it still did 3% the next 2 times. Now if there's a pattern to kb and damage then if I'm right the kb on the attack shouldn't have diminished that significantly.
The last hit dealt 16% and the original damage would have been 21% so it lost 5%. He does and f-smash and an f-tilt and when he hits with his fair again before dying he does 3% again.
He lands 3 then does 6 attacks that should mean that it should have negated or nearly negated the diminishment. Idk weird stuff. I just wish a video was posted about it. But as far as i'm concerned,the guy says that the attack must hit opponents and damage them in order to diminish.
Anyway sorry mike for answering the questions.
