I think this can be closed, looks like this works correctly now.
As a suggestion maybe a +1 on the roll itself would be more balanced, instead of acting as if you had 1 level higher in the skill.
Seems like a lot of points to put into something to just make leveling in the start a bit easier, but not really making a big difference at the end.
But take that with a grain of salt, I'm in no way a master crafter, so I might not know what I'm talking about :)
