Move silent bug?

[Farwalker]

I've been testing out the move silently skill - it may not be that useful in practice but I like the idea of it.

Anyway, I may have come across a minor bug. The description of the skill in game says that Dexterity complements the skill, but in my testing large differences in Dexterity are having no effect on how close I can get to an entity and still be "silent".

Would be nice to get a bit of help from Dex in this area.

Thanks
