I think the message here is that just because you think you've done enough of a certain aspect of training doesn't mean that you know it all.
Obviously you enjoy flying your Saratoga, Lance, Commander, Viking or Comanche (I assume that's what you own) and using it for the purpose that it is designed for. You've rather lost sight, however, of what training is all about. It is about learning and development - it's also about equipping a student with skills needed to cover a broad range of flying.
It's been said before - a PPL is a license to learn. Are you still learning? Are you still receptive to input from others? What makes you think that in 3 hours you have the answer to stall/slow flight awareness training? You wondered if you were asking a stupid question - well no, you are not. There are no stupid questions apart from those that are never asked! You just didn't seem to want to hear any answers.
RogerF gets where I'm coming from too (I think!)
Next time you need your 'flight with an instructor' drop me a line and I'll be pleased to spend a day with you. I guarantee you'll learn something (even if it's just that you don't like me!) and I am certain that your views will change.
Like Genghis I probably have more than a couple of hundred hours spent stalling and at the back side of the drag curve. I would love to share some of what I've learnt with others.
