That's a solid tip about gravel. I've noticed posts set without it often wobble or decay within a few seasons. Using crushed rock instead of smooth stones helps water drain faster. Do you mix in any sand or just use straight gravel?

Reminds me of the weeds that kept breaking through a crack in my old driveway. They were these scrappy little green things, not pretty at all, just stubborn. Every weekend I'd pull them out, and by Wednesday they were back, splitting that concrete open a tiny bit more. Makes you wonder what's stronger, the perfect lawn or the stuff you never asked for but can't get rid of.

Honestly, what exactly are they saying it can't do? I get that some older methods have their place, but if it holds strong for your quick projects, that's what matters! Is it that they think it won't last, or is it just about the way things have always been done? I'd love to hear one concrete example of a job where they swear PVA would totally fail. Sometimes tradition is just an excuse to hate on new stuff without a real reason.
