This is why I have no faith in this type of 'numerology'. If you play actual games, this will provide a representative sampling of what kind of situations will occur in the end-game. So just play a thousand games or so, starting from a material imbalance involving the piece under test (pitting it against various more or less equivalent combinations of material), and you will discover how often the piece will survive into the end-game, and what problems it will on average have to face there.
