Just curious, how valuable to people find the batting runs metric on Diamond Dope when compared with RC/27 and NERP. I only because it's the only that exports for a specific ballpark when you do the entire data dump.
Any gb-a is a DP if less than two outs and a runner on 1B (almost always--not if infield is in). A gb-b is a fielder's choice with batter safe, runner out....and gb-c is runner advance and batter out.
