Gosh, I hope this isn't referenced by anything. What did I mean to put here? When adding W to FD, I found: adding just forward move + capture was worth 0.6 as much as adding the whole W powers; forward 0.6 sideways 0.65 fwd+backw 0.7 backwards 0.2 where "worth" == "adds as much to the winning percentage". I suppose there is some value to this....
