Here's the data on the augmented knights, obtained from Zillions vs.
Zillions using 5-ply fixed-depth searches.  The augmented knights are
placed in the rook positions and played against the orthodox army.

All the augmented knights give an advantage vs. rooks, probably in part
due to their ease of development and the rook's lack thereof.  The
following values are the various pieces' advantages over the rook, in
centipawns.

ND, NA = 27
NW = 38
NF = 82 (!)

The standard deviation for these measurements is about 10 cP.
