Hello, Bright Powder's effect entry is incorrect.
Bright Powder Effect: Raises the holder's evasion by 10%. -Bulbapedia
Bright Powder lowers opponent's accuracy by 10%.
It may seem like these two are the same thing, but taking 10% away from 100, and adding 10% back would not bring you back to 100. taking 10% away from 100, and adding 11.11¯% will bring you back to 100.
Another example is Keen Eye doesn't get affected by Bright Powder.
Lastly when stacking multiple evasions whether your evasion is increased, or your opponent's accuracy is decreased will determine the second evasion stack.
Lastly lastly I could be wrong about all that ^ lol so meh. L> analytic nerds
