You keep arguing with these rankings as those they are the objective result of a sentient process. You really should stop giving it this level of respect and just move on.
Or, if you really do want to manipulate the rankings (without going the usual routes of bribing editors with advertising, paying raters to play your course, etc), then may I suggest running the Rye Playbook.
Say for example you want Pennard in. Start by digging up old quotes by Famous and Important People regarding the merits of the course. Or, even better, the club, its history, famous and important members, the town nearby -- anything on which we can hang our hats. I don't have time for all the details but basically what you need to do is find ways for tastemakers to tell raters it is great and no list without it carries legitimacy. Eventually, the groupthink fire will catch and you will have shaped raters' opinions as impressively as Uri Geller bent spoons.
It's a long process, made even longer if the course is remote. (FYI we are entering Year 6 of the Ganton campaign and although our band of admirers is small we are dedicated. Results are starting to show and it is only a matter of time before the groupthink catches.)
If the point of your exercise is to get Mach booted, then I think you're on the right track with a paired contrast. I am not sure Pennard is the right contrast though. You need to pair Mach with a more highly regarded course that people naturally associate. By singing the merits of the other course and using those merits to point where Mach is deficient, you will come to see the one balloon sink (Mach) while the other rises.
I am no expert on the dynamics of Pair-Driven Rankings Assassination, only being partway through the Ganton process (Woodhall Spa). But based on my limited experience it does seem easier to sink one than to elevate the other. (See: groundswell of opinions against WS.)
Bonne chance, and I remain, sir,
Helpfully yours,
