Does Fargo Drexler's Investigate-ability work better in certain rooms?

Thanks for playing the game!
The abililty works the same in every room, there are no better rooms to search in.

Hi!
Doing my 1st run with FD as a start char. His Investigate-ability gives me a lot of joy as I'm basically the scap king now.
I was wondering if the ability has a better chance of finding high level gear if it's used in more 'high level rooms!? For example: Is the casino-room better to use it in than in the kitchen? Is the Bridge-room the best one?
Would like to know!

Thanks,
Martin
