I think the more obvious answer is if they say at the half year that they are moving to quarterly reporting, which is probably more efficient (unless we head back into Covid turmoil), that then proceeding with Jan numbers isn't consistent with their strategy or message and thus the next reporting would be the quarterly.
not worth making a mountain out of a molehill on this nor is it any use speculating on Jan numbers being no good because they haven't been released.
