How does Choice Scarf work with Speed Swap?

Question

If my raichu speed swapped while wearing a choice scarf, would it snap-shot speed values at the time of the swap? Or would it snap shot pre-choice scarf speed values and then apply the choice bonus to the new relevant sub-totals?

If it's the former, then would knockoff drop the new speed value to 2/3rds its regular total? Normally this is the kind of thing I just number crunch and test myself, but I figured it wouldn't hurt to post it here for posterity.

Answer 1

Speed Swap exchanges the raw, underlying numbers you have without taking anything like Agility or Choice Scarf into account. When those things exist, then, they get layered on top of the new speed value, and effects like Haze or Knock Off simply do their part to make those effects not exist anymore.
