This is the book. I would say it's about A5 size.
I read the section again on transplanting, and he does indeed say the optimal time is right after flowering, but never mentions anything about roots growing more at any particular time of year. He doesn't elaborate about the reasoning, only that it gives more time to acclimate to its new surroundings. He does say that this is not the only time, and that given the right care, martagons can be transplanted any time of year and will at least survive.
I agree with your thinking, William, though as you say, there is so much speculation.
For those who might want easier reading of those link (and with pics), they are here:

I respect Göte and Leena. They are long time, knowledgeable contributors to that forum.
