There seem to be a few scientists in this discussion. Linguistics and English are not an exact science in which one can always arrive at the right conclusion by employing logic. Few native speakers will enter into lengthy discussions of that type. And I understand the reasons. They have expressed their opinions, which reflect actual usage and appear to conflict with yours, and I think that will be all as far as they are concerned. I agree with the natives;
ways, in particular, is badly off in this context.
