A few comments:
1. If the scorekeeper has nothing against your daughter, the ROEs will even out in time. Just bad luck for your DD
This isn't true. ROE is a repeatable skill. Or, more accurately, certain types of hitters ROE more often than others.
I don't see any real issue with this though. It's a stat like any other. It gives a piece of information, and it's not the fault of the stats that a lot of people don't know how to use them when evaluating players.
