Here,
here, and
here, we discussed some passages of the Gehrz translation (paraphrase? interpretation? rewriting?) of Valens's Book I, and the conclusions weren't very favorable. The observations made there are still valid, and so are Konrad's acute remark here. In other words, the concerns still prevail and the question arises whether Gehrz's work is a legitimate rendering of anything by Valens. If you ask me, my answer is a definite "no".
I also want to remark that translating old astrological texts is an arduous task. Most aspects worthy of consideration have been related by Stephan Heilen in two papers:
"Problems in translating ancient Greek astrological texts." In
Writings of Early Scholars in the Ancient Near East, Egypt and Greece: Translating Ancient Scientific Texts, eds. Annette Imhausen and Tanja
Pommerening, 299–329. Berlin/New York: 2010. (Google Books preview

Translating Writings of Early Scholars in the Ancient Near East, Egypt, Greece and Rome: Methodological Aspects with Examples, eds. Annette Imhausen and Tanja Pommerening, 507–569. Berlin/Boston: 2016. (Google Books preview

I think without the awareness of the issues raised in these papers and a clear methodological strategy, it's risky (and somewhat foolish) to produce so-called translations.
