FWIW standard RW includes whole populations not males vs females. Under the same conditions I would expect RW by design would be similar for both as it is an average of all populations.
Indeed I know the standard weight tables include both sexes. But for quite some I was influenced by others who suggested that males would tend to be of lower RW. The arguments on the face seem plausible, cull skinny males but this study is the only data available to me with both sexes documented. The RW findings were not what I expected and not what I have been taught here and everywhere else for that matter and I thought I should share this with the community. Obviously not appreciated but the intent to share the information was genuine.
