regardless, i'd like to disagree with your claim of PEDs being banned primarily due to their negative health effects.

It's even old news:
The study involved 14 runners training for the 2017 Portland Marathon, who were divided into two roughly equal groups running in either the Vaporfly 4% or the conventional Zoom Pegasus 34. Immediately before and after the marathon, they gave blood samples and completed a soreness survey. Sure enough, the Vaporfly runners showed lower levels of three blood measures of muscle damage and inflammation (lactate dehydrogenase, white blood cell count, interleukin-6) after the race, by between 15 and 43 percent. They also reported significantly less leg soreness.
Less beat up = more quality sessions = better races = new PBs, NRs, WRs, whatever.
The second part of the study involved seven of the subjects who, in random order, trained for two weeks each in the Vaporfly and the Pegasus, doing three standardized workouts per week at the same intensity each time as determined by heart rate. When training in the Vaporfly, the runners ran faster and farther—which, given the running economy advantage, you might expect. But what was interesting was that the gap widened as the training week progressed: on Monday, they were 9 seconds per mile faster in the Vaporfly than the Pegasus; on Wednesday they were 15 seconds faster; on Friday they were 35 seconds faster. This suggests that they were able to handle the cumulative training load and recover more effectively, which allowed them to train harder and faster.
Let me repeat that bolded bit once more, which allowed them to train harder and faster. I assume you all know what happens when you train harder and faster, but not get injured.
Mmm.... this sounds exactly like what is going on to me. If athletes can do more quality miles than they previously could -- without getting injured -- then their ability should increase and their PRs should fall.

2017 is calling. This was known as soon as anyone put the damn shoes on.
It's amazing there are the 10,000 left who have no clue.
Different foam.
It's like saying why does snow create more friction than ice? They're both solid water?
