The above was done with a long analysis of a position,
running a game changes things, the hash is worse but the capture
sorting works better:

hash.......: 1.09% 88.80%
null.......: 21.35% 67.28%
wcap.......: 4.97% 68.31%
ecap.......: 0.43% 43.53%
lcap.......: 4.53% 5.87%
kill.......: 2.94% 15.29%
ncap.......: 64.67% 0.43%

Looks like killers should be tried before losing captures.
