“some of the sheilahs that have come up over the past few years, and there were definitely a lot. If I have a chance, maybe I’ll post some of them, or at least the topics.”
assuming “a few” is 3 years thats over 150 sheilahs assuming once a week?
“My feeling is that if anyone does not have sheilahs at least once a week, that is likely either because they don’t know enough to realize there is a sheilah, or they are extraordinarily well-versed in halacha, so they don’t need to ask.”
I think its someone who is still new. Which is of course a great to recognize lack of knoledge and ask when appropriate even if it is daily!
“One category includes sheilahs that require a Poseik (so even if I knew as much halacha as I should, I would still need to ask).”
I am not sure what that means. Like Tzoras that needs a kohein even if the person with the nega knows the halacha?
Im not sure your distinction is correct. OF course in throry ever y body would know kol hatorah kulah. In practice this is impossible so we have a Rav to pasken that isnt a failing per se
