Does Tinted Lens get double the boost against a Pokemon that quad-resist the move?

Question

So a Yanmega uses Bug Buzz on a Skarmory who 4x resists Bug. Will it Tinted Lens be counted twice(from Steel and Flying resisting Bug Moves) or once?

Gligar doesn't 4x resist...

i thought ground resisted but for some reason :3

Answer 1

Well, I used a 0 SAtk Tinted Lens Yanmega on Showdown with LeBoss.

• When Yanmega spammed Bug Buzz on a Skarmory, it did about 25%.
• When Yanmega spammed Bug Buzz on a Skarmory that just Roosted, it did about 50%.

So Tinted Lens does not quadruple the power, it just doubles the power.

Answer 2

It would be half resistant because it doubles power for not very effective moves
