What my point is is that the actual rules matter only in a handful of situations. Most staff apply their own version of 'common sense' as you allude to. This means they will either use their own set of made up rules just because that's what they have always done, or they will just accept what looks reasonable and reject what doesn't regardless. In some cases, this document of yours will have an influence yes - but the ticket in your example passes the duck test of looking like an Any Permitted Anytime Day Single, thus, given there isn't a TPE ONLY Anytime Day Single for that flow, probably being an Any Permitted Anytime Day Single. The fact is that the rules laid out in your document that I don't have access to don't seem to form part of the conditions of the ticket that you end up with post-excess. At least, that's all I could garner from that thread you helpfully linked to.
