While finding the calculation of RPVs a fascinating theoretical challenge, from a practical, playing, perspective the RPV or quantative piece value is only part of the story. In play the qualative value of a piece has also to be considered. This being so it might be said that assigning RPVs to accuracies beyond 0.5 is spurious. It is enough to know that a Rook in FIDE chess is worth 'about 5 pawns'.
