I am truly not sure where I stand on this overall thread issue. But, the notion that comped rounds would not affect rater bias seems ludicrous. I am a physician and I hear all the time that drug company freebies do not affect my colleagues behavior. I say "baloney"....Drug companies are too big, too smart, too powerful to not be quite clear that giving free lunches, pens with company logos, etc must change physician prescribing behavior. Likewise, I believe it does impact the ratings for comped golf, food, etc...I also believe that the quality of the course may far outweigh the effects of the freebies, but when courses are only marginally different the freebies might just make the difference. There might be good reasons for allowing comped rounds, BUT the raters need to be ever conscious of the truth...free just might sway their opinion, if only a little bit.
I am not a course rater. Full disclosure.
