From conversations with airline pilots over the past 25 years I would say raw data (meaning no FD or autothrottle if you are serious) flying is rare. Seems from talking to first officers some captains are basically frightened of switching off the FD (perhaps "apprehensive" is a better term) and will refuse to even let the F/O practice a simple raw data climb or descent or approach - even in CAVOK. There is much lip service to the advisability of keeping current on raw data but that is all it is - lip service. Few seriously believe it. Part of the reluctance against raw data is loss of face if the instrument flying by the captain is let's say "rusty." If the F/O raw data is rusty the captain is free to criticise but it is a courageous (read foolhardy)F/O that laughs at the captain's raw data attempts. Company SOP rarely encourage raw data -the usual reason being we have paid millions for sophisticated FMS, so use 'em.
