Film choice and developer also will play a role. If i had a very wide range, I would develop using a two-bath method which I have reached 13 stop latitude with (Fuji Acros, Pyrocat split bath) and for normal scenes with 8 or less stops, I just expose slightly under the average to maintain shadow detail and have no issues with it thereof. Check out my BW Kiva shot for an idea about what split development can do.
