WARNING ! GEEK ALERT ! THIS THREAD CONTAINS ACTUAL MATHEMATICAL FORMULAE ! 
On a number of occasions when crafting items, I've been asked to predict the durability. Unless it's something I craft all the time, I'm unlikely to know. The durability on a crafted weapon or piece of armour increases with every 1.0 of crafting skill obtained, so it's hard to keep track. It seemed to me that I might be able to work out a mathematical formula that would help me calculate what the durability would be (yeah, I'm sad, sue me ).
I came up with the following equation. To use it effectively, you need to know the standard durability for the item concerned (e.g Dagger 1200 dur), and to round down your crafting skill to the nearest whole number (e.g 42.3 skill = 42). Actual crafting skill is the skill of the crafter concerned in that particular craft, Required crafting skill is the minimum skill needed to make the item, and % Increase is the durability above the norm which you can then convert to an actual figure.
(Actual skill x 0.75) - (Required skill x 0.75) = % Increase
It also works as :-
(Actual skill - Required skill) x 0.75 = % Increase
Head exploded yet ? Dropped off to sleep ?
Well here's a few practical examples :-
The normal dur on a Dagger is 1200, my Weapon skill is 80.1, and the Required skill is 0.
(80 - 0) x 0.75 = 60%
1200 + 60% = 1920
Therefore, the dur I'd get on a Dagger without enhancement would be 1920.
The normal dur on a Great Axe is 2000, Required skill 25.
(80 - 25) x 0.75 = 41.25%
2000 + 41.25% = 2825
So far, this has worked on everything I've tried it on, but the formula is still in beta trial so I'd appreciate a few crafters play testing it.
Now, in the unlikely event anyone's read this far, they will note that this formula is only of limited usefulness. However...it then occured to me that, with some tinkering, I might be able to work out the exact skill required to craft the newer items which, to my knowledge, is not yet listed on any web site...
This does get a tad complex, so I'll end this post here and post again as "Crafting Skill Theory"
