Is a building with 18 floors and a massive layout, which makes finding errors more complicated than going by zone on each level. Our process is with a plugin where we need a host to insert studs, king studs, and header. That's the reason to need the walls. Now we don't do copy and monitor normally because requires setting all the templates and is easier to miss any error because the walls are not always modeled until deck height, our studs don't always work perfectly for any wall opening or wall edit so we have to fix those before our studs come to play to be more accurate.
I try to use copy/monitor (I'm new in the company) per zone in the level so I can copy walls faster rather than selecting each one in the zone I need to work, that way I jump one step and move forward to a better/faster way
Also, for some reason, the coordination process depends on matching contract documents (yes, the ones that come from Revit models) so I have to move walls to match any dimension they have in those documents (yes dimensions that should be the same but sometimes human error comes and select another layer of the wall, and yes I have to now use that wrong dimension). But I still need to proper model the walls because they are not always reaching deck, correct ceiling or other stuff.
