You attribute views to me that I haven't expressed. I did not say or even imply that Jakob has "no limitations" in the 5k. But the limitation that affects him in the 1500 does not apply to the longer distances, and that is his relative lack of speed. In the 1500 he is vulnerable to faster athletes (those who have better sprint speed than he does, and only slightly less endurance), whereas that isn't a problem for him in the 5k. (Or 2 mile, or 3k).
My point about the World Championships being competitively equivalent to the Olympics (if not quite the same status - and that is largely because of history) is that both championships draw upon the same pool of athletes; it is a worldwide competition. I don't accept that some athletes - Jakob? - don't perform as well in the World Champs because they don't give it the same priority. I don't think either El G or Kipketer, who both had an impressive World Championship resume, would have taken that view.
You are quite entitled to enjoy your experience of Budapest but as I have a rather different view of the sport than you I don't share that pleasure. I am not a supporter of doped sport - and that is most elite and championship sport today. The feats I observed at Budapest were impressive but I remain sceptical as to how they are achieved.
