The change from oWAR and dWAR to ndWAR and dWAR is confusing folks, so I'm making an additional change.
afWAR => Average-Fielding-WAR. The player's WAR if they were a league average fielder, or what you should use if you trust no fielding metrics.
dWAR => Defensive WAR thanks to fielding and position.
afWAR = batting + baserunning + DP's + replacement + position
dWAR = fielding + position
(NOTE POSITION IS IN BOTH OF THEM!)
afWAR + dWAR does not equal WAR as you'll be double counting the position adjustment. And on a team level you shouldn't be using WAR anyway to determine what your team is good or bad at.
I'll start adding version numbers as I make tweaks to the system. This one changes no numbers, so it really is just a naming convention.
