I would subtract the number of courses from the average rank, and rank by low score. It favors the architects with the best average rankings, and slightly favors architects who have done more courses in the top 50, which I think is fair. My results:
Name - # Courses - Avg Rank
Dye - 8 - 20.5 - 12.5
Doak - 5 - 26 - 21
CC - 4 - 18.25 - 14.25
Fazio - 4 - 24 - 20
Jones Jr - 4 - 39.8 - 35.8
Kidd - 3 - 23 - 20
Jack N - (3?) 35.3 - 32.3
My rank would then be Dye, CC, Faz, Kidd, Doak, Nicklaus, RTJ2.
Feel free to disagree, just one way to look at it. Of course, if we had the size of the marketing budgets, that might alter the outcome.
