No, I'm not trolling, nor am I suggesting that Boston performances should be omitted in a subjective consideration of an athlete's career. By the rules of the sport as they currently stand, however, they most definitely should be omitted from any attempt to make an objective comparison between histories of performances on unaided courses, which is what I did in showing that Dos Santos and Sato have career records superior to Hall's on such courses.
Fair enough, but I would suggest that it would be a rather subjective decision to select only that factoid when predicting their performances in Chicago. Again, do you think people were discounting Robert Kipkoech Cheruiyot's 2:07 in Boston 06 when predicting his performance at Chicago 06? The actual result certainly shows that would have been a mistake.
I also think it is disingenuous to cite his "career top five" on record-eligible courses, when he has ONLY run 5 times total on record-eligible courses. In fact, should the 2:09:02 and 2:10:36 even be on your list? I am not sure those were record-eligible either. This list -

It seems what you are really analyzing here are athletes' choices of which marathons to race, which may be an interesting discussion topic on its own, but I am not sure of its relevance when analyzing the Chicago field.
