I don’t disagree with you. Most club golfers in England are brought up with a stableford mindset. They talk about nett scores, how many blobs etc.
Check out most clubs starts sheets. Stablefords will be over subscribed, medals rarely unless club champs etc
That explains a lot doesn't it, lack of ambition and desire, I'd also bet there are few cat 1 golfers playing stableford every week.
