What I said, and I believe we are deep in the detail of ticketing here, is that (colloquially) if you end up travelling in the class that you originally paid for (ie your GUF1 is refunded to you), you don't outright deserve 75% of your original fare back. That the legislation works differently to my view is something I learned in the course of this thread - as noted above I've never been downgraded from any fare/ticket construction.
