As a programmer, I'd say that the better results you get in the test when considering both pawns as passers is due to the fact that, I the tests, you get the best results when giving high values to what is tested. So, in a test about passed pawns, you'll get great results if you give very high values to them, but that won't help much in real play. José C.
