I would think 11+ would be more logical than 12+, since you are permitted to open one of a suit by agreement on any hand with 11 points, and it is the smallest such integer. Happily this is also -- provided we are considering first or second seat openers -- independent of the level of permitted agreements. The case for 8+ presumably is the corresponding statement with "some" rather than "any".
It is generally accepted that the minimum high card strength for a one-level opening bid depends at least to some extent on distribution. Unfortunately the clause in the regulation makes no acknowledgement of this fact.
My logic for 12+ is that with the least distributional hand possible, a 4333 shape, "the normal high card strength associated" is 12+ HCP (Yes, it is permitted to agree to open a 4333 11-count, but it is not normal to do so.
My logic for 8+ is that is the absolute minimum permitted and I can construct extreme distributional hands on which it might be considered desirable to open at the 1-level.
However, as I mentioned earlier, there is also a case for 9+, 10+ and 11+; I see that a case has already been made for each of these criteria in the replies we have had to this topic thus far.
Interestingly, if an interpretation of this clause of the regulation were ever to be the subject of an appeal, I don't think the AC should ever be entitled to over-rule a TD's reasonable interpretation of this regulation, as the AC would not have any grounds for ruling that the TD was demonstrably wrong.
