I agree this list is not a judgement value about who had a better career. This list says absolutely nothing about someone's career.
Right. I mean, guys like Coppi, LeMond or Gaul don't even appear on this list. It just is what it is, and not more than that.
I only asked the question, because there's a kind of logical ranking in this list. Otherwise you can make it on alphabetical order.
I think it makes sense. Like the way Olympic medals are sometimes counted by just adding up the number of medals per nation. If the goal in the podium slam is to just get on the podium in all 3 GTs, then 4-2-3 should rank higher than 6-3-1 or whatever.
