@Dax00: I agree completely that calculatory methods for piece values are usually no good. They qualfy as 'fact-free science'. The known values of the six orthodox pieces can be reproduced by infinitely many numerological recipes, which can be designed to give arbitrary values for any fairy piece.
I therefore do always determine piece values in an empirical way, by having a computer program play games in which the pieces are pitted against a combination of pieces of known value, and measure their performance. Through such measurements the Gryphon turned out to be worth about 8.3 on 8x8 (IIRC), on a scale where Q=9.5.
