I was looking for the best offensive type combination and I came across this image. The defensive part was good, but the creator fucked up on the offensive part. Do you see it too? I'll spoiler it in case you want to test yourself.

That's right, for some reason, some dual typings are ranked below the pure ones. This is dumb, because having another STAB option is always better than only one. The creator probably used the same method as the defensive section, but it does not work in the same way.

So maybe we can try to fix this and come up with a proper way to rank offensive typings.
