Pat,
What I am trying to say is this; at present course X is a perfect 10.0 in my evaluation for memorability of par 3's. A few years later I am fortunate to play CPC, which now, given my new perspective is a 10.0 in the same category. By comparison, course X is no longer a 10.0, and falls to 9.75. Is this not possible? The experience at CPC opened my eyes, and proved that architecture can reach another level. If this process cannot occur, can you ever give a perfect 10.0, because this precludes you from saying anything is better, ever.
Your right about Augusta, my rating for the "basic conditioning" would alter greatly if I played it consecutive years, first in April, and then in winter. Wouldn't that change the rating I give the course, causing an overall numerical rating change the next year, even though the architecture had not been meddled with.
