TBH I also wonder how accurate those lining measurements are and if they are just an approximation since (at least in my case) they only measure it once on the screen (as opposed to taking several measurements and averaging them) and it is susceptible to user error and interpretation. I do not know about the estrogen part of your question.
Thanks. I also wondered how accurate the measurement was.
