Kzg,
I would completely agree with you. Doing the PRM, or getting any other letters after your name for that matter, have little measurable value in the short term. In particular the delta between when you don’t have the PRM and the instant the email arrives advising you of the results is practically zero. That applies to just about everything else too – a CFA, an MBA, a CPA or anything else. These things always pay over the long run, and even then the value can never really be isolated and attributed to your education or certification.
Completing the PRM does give you a great deal of confidence as you are sure that you know, or know where to look, for many of the commonly encountered issues in risk. It gives you the theoretical bedrock, though of course practical life is always different from the text books.
While the value may never be measurable, I can guarantee that the only risk is to the upside and none whatsoever to the downside.
