Crafting and Wis/Int?

[Sethius Marlowe]

I apologize if I'm completely blind. I didn't see any sort of crafting forum to post this in here, so I'm sorry if I'm in the wrong place.

I was wondering if anyone had any detailed information about how wis/int affects tradeskills? I know the basics, that it uses the higher of the two stats (is this correct?) and that a higher stat will allow quicker skill ups... But do we have any sort of numbers?

I know this would have been hard for someone to have mapped out, but I figure enough time there might have been someone who was ambitious enough to level a skill from 1-255 on two separate characters and document it or something.

I guess what I'm truly wondering is how big of a difference are we talking about? Does +70 int = 35% faster skill ups? Or 5%?

Thanks for any input or advice. And again, I apologize if I completely missed some obvious thread about this.
