At face value your first post could indicate that you are serious.
However
You are anonymous.
You give no details of your industry background.
The relationship between Vmo and Vd is a matter of regulation and flight test.
You ask people to give their views based on their experience when by definition they have no experience of what you are asking about.
You give no indication of what you intend to do should anybody respond along the lines you request.
So please don't hold your breath.

Excellent post, JF, and well said. I'd wager that "Ralph" will not offer up any credentials lest he/she reveal his true identity, as pointed out by ADDIS77. It appears "Ralph" is seeking confirmation from outside his/her own collection of "expert" pilots, which is indeed an infinitesimally small sampling of aviation professionals. He/she will not get the confirmation bias he is looking for here, so will proceed to bad-mouth and denigrate this forum in other locales. Bet on it.
