contradiction in the wiki

[Icy]

OK so bless stone increases success only by 2%.

Another thing in Enhancement_Stones:
"Examples of this: You have a +2 Weapon and using a lucky stone on it to try to enhance. There will be a 17% chance you will enhance the item to +3. If you are successful at enhancing the item then you will have a 35% chance of getting the weapon to +4 instead of +3"

But lucky elrue[1] which is the more succesful has only 13%.
The 17% is a mistake between lucky and bless or there is a mechanism that i missed?
Thx for your work! Wiki help me a lot.

Blessed Elrue[1] increases success rate by 17%, the Lucky Elrue[1] counterpart increases it by 13%. And if you use Lucky Elrue[1], 35% of the successes raise enhancement by 2 levels.

I find the "Lucky Sucess Rate" misleading - what about the inherent rate of success? Currently, the probability listed is just P(lucky stone's contribution to success) * P(getting lucky when successful). However, there's also P(inherent probability of success) * P(getting lucky when successful).
