Actually besides #7 (as I never did PPE on either of my mares) and #4 (I had enough quite time to mess with them) my answer would be "No" to all of his points. I'm not heartbroken though (and my mares are with me for over 7 years already).
I'm NOT saying he's wrong though, just saying it's not always correct.
