Well, but inherited runners are not all the same. Runner on 3rd with none out isn’t quite like runner on 1st with two outs.
One thing that I’m curious about and I don’t even know if the numerals are there to suggest anything about it. Are RP these days more apt to enter a game at the beginning of the inning rather than after the 1st batter of the inning? It seems likely, but I don’t know for sure. And how does that stack up to previous years/eras?
