from the LR archives we find that 2010 was when monaco did a resurfacing. this is when the fakeness started.
1m short in lane one. doing the math at different m/s values you can see how at 3:35 speed which is around 6.7 m/s will give you 2 seconds as you are running 1497 meters instead of 1500m. look at all the people who ran their PRs at monaco then compare their other times at track meets and you will see the issue.
i did the math for 12:30 for 5k pace on that track, and being 1m short you get 25 seconds off....and boom you see ol cheptegie runs about 12:50s....all those thinking he would crush that 1500m earlier and only ran what 3:37? well at monaco he would have only run 3:35-36.
now think about the 10k. do the math and figure out what 26:40 pace is on a 1m short track and boom its like 26:10.
i did a whole write up on this and my comment was erased. but i would wager you find people running the 400 in lane 1, and thats their PR or SB for that year.
lets take a look at the top 25 times in 1500m, then take all those who ran their times at monaco since 2010 then find their other times on other tracks and you see the 2-3 seconds. the only way this works after lots of thought is the track is 1m short.
