That's a very helpful post, so please don't take my little nitpick the wrong way, but, the way you've written it looks to me like you might not realize that your test wallet actually does match the 12-byte pattern from the post that you're responding to (if you look carefully at your screenshots, then you'll see that your 7-byte pattern turns into the longer 12-byte one as you keep scanning left).
Nitpicks are very much welcome specially those that can correct mistakes with good explanation. (
I miss o_e_l_e_o)
As for your take on the context of my reply, perhaps because the matching pattern is not mentioned.
In this case, it's a per-person basis based on how they think individually.
