I specifically said "the 1980s times of Cram, Coe, Aouita and even Ovett".
Like Armstronglivs, I also explicitly wrote "if"; more specifically "If we assume, as you do, ..."
I don't need to know how clean the 1980s were, as the context was clearly conditioned by Armstronglivs' "if any of them (Coe, Cram, and Aouita) were clean, this suggests ..."
Your facts still fall far short of allowing us to connect blood doping, or any doping, to 1500m or mile, world record level performances, that would allow us to conclude "doping is necessary for a world record" without relying on elements of personal faith.
The 4 blood doping points may have been backed by scientists, but you, and they, have not linked blood doping to the mile, or 1500m, world record level performances.
The Sunday Times 2015 article was for medal winners between 2001-2012 -- none of those times were world 1500m or mile world records.
Furthermore, we know many of these blood doped 1500m medalists were Russian women on steroids (who also did not set any world records), which artificially inflates the blood doping suspicious percentages, and confounds any attempt to make a correlation of blood doping for the men.
Another fact about Kiprop -- he got 2.5 seconds slower in 2016 and slower again by 3 seconds in 2017. Was his 2015 performance doped? When we don't know, I call that faith.
Another fact which may or may not be connected to Kiprop's positive test: Erik Boye has written some disturbing things about EPO Urine test false positives, and the difficulty for athletes to fight against it.
