We do not have multipliers.
I'm certain that the knockback Monado Smash and Monado Shield TAKE is just a multiplier at the end. Monado Shield actually takes moves below their base knockback, and Hyper Smash can be 1 hit KO'd by certain high base knockback moves at 0% (this is why we also know that it's a multiplier and not a weight change). Now, the kill percents of Hyper Smash dealing knockback are actually somewhat similar to the kill percents of Hyper Smash taking knockback. However, when Hyper Smash is dealing knockback, there are obviously no 1 hit KO's or anything even close to that.
I think a decent representation of this is the first hit of regular or mighty air slash. The move is purely weighted base knockback. Characters go the same height with it whether hit by buster or smash. However, if Smash or Hyper Smash is hit
by the move, they do change the height. We might be able to use this to figure out the multiplier that Smash/Shield have with their knockback taken. Just set up a custom stage, take pictures, and compare height differences in order to figure out the difference. We could do it with both mighty air slash and regular air slash and compare results. This might not work, because it could be something more complex than multiplication... but it's worth a shot!
I'm not sure what is changed in the knockback formula for Smash/Buster dealing knockback. It looks like the moves of Buster deal less than their base knockback, so I would think a multiplier after base knockback in the formula... where the r is. However, Smash does not come anywhere close to one hit KO'ing people, as it would if it was just a simple multiplier. Perhaps there is a different multiplier applied to base knockback and knockback growth!

, do you know how weighted base knockback works with the formula? I can't find any information about that.
Also, @

, could you fix U-tilt's active frames in the frame data? The first U-tilt hitbox is from 11-23, not 11-12. That hitbox is for the red, metal part of the Monado, while the other one is for the beam. They both last until frame 23.
