Please find attached an extremely crappy graph I made showing all who have run sub-3:30 more than once. (There are 18 others who ran under 3:30 a single time, which I excluded only because it would have stretched the graph out way too far and cluttered up the names. Sidenote: Daniel Kipchirchir Komen is different than Daniel Komen, who only ran sub-3:30 once!)
It's fun to see a superstar wipe the floor with everyone like Jakob has been doing, but here is a great visual reminder of how far he (or anyone) has to go to surpass El Guerrouj. Jakob will need at least another 5 years at the top with multiple Olympic and WC wins, not to mention WRs, before the conversation will be worth having. As of now it's hard to say he has even completely surpassed Cheruiyot!
