You're making my point for me, saying table tennis is "just a proprioceptive predictor" is dismissively reductive (and not a particularly useful framework for understanding table tennis), even if it is strictly speaking accurate. It's the sort of thing someone who has no idea how hard training for table tennis is would say.
Let me put it bluntly. I’m agreeing with you but saying that isn’t what I was talking about and trying to give examples. You’re also agreeing with me.
The “idea” of table tennis and the rules. Those are things we can talk about. It’s those “best practices” I gave in my example. The actual playing of table tennis would be the examples. How to apply those best practices and what good code looks like.
