Effectively the same as the WR for the marathon progression time. Most of the reasons for it have already been mentioned.

And we know the Kenyans are squeaky clean, right?

If they know their speed is being used as a gauge on doping they work around it in many ways. The real number people should be calculating now is the time to capture the break based on the time away from it and the speed of the rider in the break. This one is less fudge-able because if they let it go they could lose actual real time/win.

...Therefore the graph you have posted could, without any statistical confidence, be said to be indicative of a period of high blood doping from the early nineties, gradually reducing from the early 2000s onwards.

True but if it takes the same shape after the spike as before, then you have to conclude that whatever caused the spike remains. Say the natural progression curve was very gradual, for whatever reason: the speeds listed in the OP would still look jacked up. Again, looking at the eighties numbers would settle it. The natural curve would presumably be steeper at that point anyway.
