Gee:
I think you have missed the point.
I am comfortable with the OffInt "extending" (d); I've read it; I will apply it; I think K should, too.
I understand your explanation of why you think what you think, it makes sense, although I am conscious that you have never cited any persuasive published authority for your "why" explanation [meaning the "advance base" issue, which is what has K all excited], nor do I see the need for some of the interpretation you insist is necessary.
However, as [I think] you just wrote, I can easily ignore our difference of opinion, since it will make no difference on the field of play. Both you and I will get the play right if it happens while we are on the field. Consequently, I see no point in debating the issue just for the satisfaction of "being right": "A distinction without a difference makes no difference". I make room for the possibility that I might be wrong; even if you don't [ & I make no assumptions about that], we end up in the same place.
