Take a look at page 14-15 titled Pharmacologic Studies of its Estrogenic-like Properties. http://puresterol.com/wp-content/uploads/2015/04/B.-Review-of-the-Efficacy-Safety-and-Applications.pdf
If one compares the potency of various phytoestrogens, including genistein and miroestorol (from standardized P. mirifica root extract) to estradiol, according to the work of Murkies and colleagues (Murkies, A.L., Wilcox, G. and Davis, S.R. Clinical reviews: Phytoestrogens. J Clin Endocrinol Metabol., 1998; 83: 297-303.)
the relative potencies would look as follows, with estradiol arbitrarily ranked 100:
Estradiol = 100
Miroestrol∗∗ = 3.3
