Mike, you've struck an interesting chord.
I've played miserably at a few Top 100 courses (especially when I'm just off a long flight or a 3+hour car ride) and not once have I knocked the course for it. Personally, how I play is of little influence, if at all, for how I evaluate a course. The best personal example was the first time playing Crystal Downs. After shooting 15+ over my handicap, and missing the right angles and nearly every line of charm, it was abundantly evident that I'd experienced exquisite architecture that more than excited my critical senses. Same for my first round at Eastward Ho. To this day, both remain two of my all-time favorite and strongly-ranked courses (and don't think I've ever scored particularly well at either!).
That said, I've also been witness to other raters, who's poor playing has ultimately resulted in lower considerations. A good story was the time a foursome (with two GD panelists in tow) at a wonderful well-regarded Walter Travis design. Both single-digits, neither GD rater broke 85 that and walked off muttering how "mundane and pedestrian" this terrific design was. Of course, their vaunted short games fell apart when they perpetually left themselves in difficult spots and on the wrong side of over 10 greens.
I suspect the converse is true as well, as I've seen a great-playing round by a few well-esteemed panelists reflect a higher-than-deserving rating. One GM panelist in particular, had a stellar scoring day and walked off a famous recently restored NJ course and proclaimed it "inside the Top 50!," much to the surprise of the rest of us.
Human nature and confirmation bias seems to be a tough moat to cross.
