I hadn't noticed that the article was written in 2011. So, in this case, Eaton and now Kevin Mayer or Damian Warner, could be great additions to the list.
Thank you Clay for the note and thank you Janek for bringing it back to the forefront.

Clay, thank you for your excellent and detailed work.
Taking account about the inclusion, in the list, of some men who do not compete in Decathlon, I consider that Ashton Eaton must be in any list of best of all times. One reason: he is the monster of Heptathlon (the multievent indoor version of Deca) in which he is the World Record holder and the most dominant men in history, adding to this, his two Deca WR, his two OG wins and the =OR, plus the two WC wins.
In my opinion, he deserves a space in the upper top of the list.
In the statistics side, he has the second-best Ideal Decathlon (Decathlon based on PBs), only behind Dan O'Brien.

Janek... the records previous to 1920 were calculated using the 1912 tables. The Nilsson, Ohlson and Klumberg's record used 1920 tables.
The Wickholm's record is inserted because his result with 1985 tables is better than Wieslander record in Stockholm.
