It sure would change, but I've never booked a schedule that was that tight where I had to hurry with set-up and tear-down.
When I was doing clinics, and we had multiple arrangers plus a sound system, the store guys always took in/out the gear for us.
The most personal gigs I did in a day was three, and they were well spaced apart.
My motto has always been, "Life should be sipped, not gulped".
