That's only if you assume unlimited paper towel stations. In reality hand drying is the bottle neck. So if every sink has its own dedicated dryer it will speed things up.

"every sink has its own dedicated dryer"

Exactly. Sinks seem to always outnumber dryers by a wide margin.

Don't ignore the folks who actually don't want to airdry their hands.

I soap, wash, shake and wipe my hands in my pockets as I walk out the door if I'm in a hurry.

But you wouldn't get a queue for paper towels. People would grab 2 or 3 towels and move aside.

Maybe but there's a bit of a shuffle getting around people who have grabbed towels. And there are always the people who stand by towels to dry because that's where the trash can is.

Actually, I guess separating the towel dispensers and trash cans in existing bathrooms would be a smart efficiency move since it would encourage people to grab a towel and keep moving.
