Change most/all items to 2x rate?

These are my current settings, and I am trying to make my server into a 2x server. That means that wood, stone, metal ore, and high quality metal ore will be 2x. I'd also like to make other things such as cloth, animal fat, sulfur, bone fragments, etc. at 2x.

Oh yeah, I also don't know how I should set the excavator settings so they're 2x, do I just multiply those numbers by 2 and call it a day?
