My experience is that it takes even longer than that especially if the 
area contains small houses rather than bigger buildings. Drawing them
all is very slow compared with inputting addr data. I'd say 10-20x.

So true. 

With the experience of tens of thousands addresses survey, this is really 
big obstable. Some of my surveyed data rotted(!) because the drawing delay 
hindered immediate input. That is, I lost the near-term memory about 
details before I could draw all the building I could easily survey 
addresses for.

This is also the reason I really get almost angry when people oppose 
importing building without addresses (because they find them "useless" 
without other details such as addresses included already during the 
import). I doubt that such people have much experience on surveying 
addresses and trying to draw the buildings while inputting the addr data 
to OSM.
