A thought about the heat treating of these hypereutectoid steels. As changing the carbon content in such would only change the amount of carbides, not the composition of the carbides and matrix (well, in theory at least), could it be that the smiths who were good enough with keeping the austenitisation temperature just so where then presented with a steel which might have been more predictable in how it reacted to the heat treatment?

Such could, I guess, result in a slightly higher overall quality amongst the blades which weren't more or less obviously botched.
