Don't forget that during this debate we found out that the North African 5000m data was wrong and understated the massive epo era gains.
"Method:
All of the raw data comes from listings at "
www.alltime-athletics.com" as of 15 Jan 2018, including performances that were annulled due to doping.
I counted "performers" and not "performances". If an athlete has multiple performances, I count only the best one.
I chose the cut-off as the average of the top-5 performers before 1 Jan 1990, as the massive drop in times started after 1990.
From this cut-off, I calculated two simple measures:
1) Quantity: A simple count of how many athletes performed better than the pre-1990 top-5 average.
2) Quality: Improvement, as a percentage of the pre-1990 cut-off, of the average of the post-1990 top-5 performers, if 5 existed, or the average of all of them if less than 5 existed."
"North Africa (Top 5): 12:50.06 1.5%"
1.5% of 12:50 (or 770s) is 11s or 13:01 but we will see this is an impossibility

5. 13:25.26 Abderrazak Bounour ALG Firenze 13.06.1984
Off the top of my head this is an average of 13:15.6 or a gain of 25.5s or 3.4%
