Apartment Turnovers

So this weekend we're painting 20 or so apartments, some up to 3 level 4 bedrooms.

I have a power roller setup, on my small airless sprayer, and some 18" rollers going as well.

Beyond this--any ideas for doing this very, very quickly? The ceiling is the same color. We'll cut in around plates. All will be done in a standard flat which matches the present paint.

I suppose two specific questions I have are

--would using a 3/4 inch nap help to go fast?

--will taping the baseboards with 1.5 inch tape (and no paper) help with speed--could we reasonably get by not taping?

I've painted for 20 years, off and on, and have done turnovers before, but would like to speed things up as much as I can.


Thanks for any input.
