I wrote to CRT when the T&C changes came in, and they confirmed that, as they put it, the clock gets reset every time you go back to your home mooring, so it's perfectly possible to return to the same pub every weekend, or spend time in other areas close to home regularly. It's only common sense, really, as most home moorers can only go short distances most of the time.
Whether you could go and stay in the same spot for a fortnight, nip home for a night, and repeat endlessly without CRT getting stroppy is moot, however (not that the OP wants to do that, anyway), as the statutory right for 14 days in a place is only for those without a home mooring.
