Focused Trance and Enchanting

[Ughbash]

The Lore mystery of Focused Trance lets you focus on something, go into a trance and then get a +20 on an intelligence based skill.

Could this be used for the Spellcraft roll for enchanting?

What about for the Craft Armor roll for making a suit of armor?

There is no rule for this. I assume the check is being made during the entirety of item creation, just like craft checks instead of something done at the end.
