Blatant and intentional misinformation has been exposed. If the recommendations had any credibility, then those recommendations were defined by numbers - especially specification numbers. Outright lies, myths, speculation and fables are promoted subjectively.
The challenge is quite simple. Post the specification numbers that justify that recommendation. Or expect engineers. who have probably been doing this stuff before you were born, to blow the whistle.
Where are those always required numbers? Still not posted. A first indication that those recommendation only come from emotions; does not come from where honesty exists - specification numbers. Show me the numbers - will text that says why that number is relevant.
