Is there any official (or semi-official) clarification on how often Psychic Virtuoso allows a character to use occult skill unlocks?

The description of the Psychic Virtuoso feat from Occult Adventures states "You can use all of your occult skill unlocks more often and you are more talented at using them." However, the Benefit section only lists a bonus for using them, nothing about using them more often. I cannot find any errata or clarification for this feat indicating either it doesn’t actually let you use occult skill unlocks more often or, if it does, how often it allows a character to use them.
