That means two scores are associated with each evaluation feature. The "computational expense" can be reduced to near 0 if you feel like it (mixing two 16-bit values into a single 32-bit integer). Maybe the main drawback is that features are evaluated regardless of the position. Of course you can make exceptions if you like, but that somewhat defeats the original goal. Fabien.
