Efficiency of Mapping - Experience for each Monster type (White Blue Yellow)

Hope someone can answer.

I am trying to work out the efficiency of mapping.

If I have met the map objective, but still have a lot of monsters (ie Blues and white packs), is it more efficient from an XP and time perspective to leave the map for a new one, or to kill as many of the remaining mobs as possible?

In other works is the XP from the Rares and Bosses enough more than 50 or more trash mobs to justify just finishing the map once "Completed"?

I have seen many graphs of XP vs Player Level vs Map Level, but never broken down by monster type.

Level 100 Merc here - Yes, it is more efficient to leave the map once you have killed all rares **AND** made sure to run all the breaches on the map, from an XP standpoint.
