This pawn, worth 255 centipawns, is on the 7th rank (it has advanced 5 times): ranks advanced = 5, value = 2.547 This pawn, worth 1035 centipawns, is on the 8th rank (it has advanced 6 times): ranks advanced = 6, value = 10.347 Therefore, it is a queen (if you so choose). However, I thought about it, and my 10.347 bonus is a gross error. That is because the +10 is already built in once the piece turns into a queen (if chosen). I did not make my nomenclature clear (obviously).
