I tested it on my Japanese White Version and Fire Fang didn't get the double boost from Sheer force. Damage Calculator I usedDangerous36M has uploaded the latest episode of his Metapodcast,
where he pointed out that Sheer Force boosts the elemental fangs TWICE.
I didn't find any information in here or on bulbapedia about that, and it
definitely needs to be tested. I mean, it would make sense, since for example
Fire Fang has a chance to burn the target and make it flinch.
