I’d be curious to see the number of trips given off FSB that could have been covered just fine by one of many on SC.

Having someone on FSB just generates unnecessary urge by crew desk to use them while they’re on the hook. Usual tactic is to DH them before they expire to cover a trip in another domicile the next day so they “save the bullet” there. Just in case. Bet if SC paid 5 hours to show in <1 hour they’d see comparable response.
