Those are great points and I am glad to see the research.
Yeah, over time sculpters have taken "liberties" with scale in order to gain greater detail in the miniature wargaming world. I have been seeing the same "liberties" taken with ef figures. There is nothing wrong with it, in my opinion, but when asked what the base scale of our figures are, I always reply with 28mm. In my mind, it's the closest.
Regardless of scale, having fun with the game is really all that matters.
