First the rules:

Silent Hunter : Elves are renowned for their subtlety and skill. Elves with this racial trait reduce the penalty for using Stealth while moving by 5 and can make Stealth checks while running at a –20 penalty (this number includes the penalty reduction from this racial trait). This racial trait replaces the elven magic racial trait.

If people are observing you using any of their senses (but typically sight), you can't use Stealth. Against most creatures, finding cover or concealment allows you to use Stealth. If your observers are momentarily distracted (such as by a Bluff check), you can attempt to use Stealth. While the others turn their attention from you, you can attempt a Stealth check if you can get to an unobserved place of some kind. This check, however, is made at a –10 penalty because you have to move fast.
Note emphasis mine.
So an elf with silent hunter who successfully creates a diversion using bluff is at a -5 penalty to hide?
