Obviously that would influence the comparisons. That is an additional variable that could be used in any comparison, but not a necessary variable in my opinion.

"Influence" is a mild word: when you factor in credit card usage, it radically changes the numbers. It is NOT an equal variable in the three major programs. Any top-tier member seriously running the numbers would absolutely factor this in - at a minimum, using the card at the hotels.
Am I beating a dead horse here? Am I the only guy here who carries all three cards? (MR Visa, HH Amex, SPG Amex) Do other frequent hotel guests just ignore the cards altogether?
