.81 for 70-80, .85 80-90, .84 90-100m according to those numbers. The time next to the 80m time is the 80-90m interval time.

The smaller the distance the smaller the time diff but there was a big drop in 30 times when Ben ran 3.80 in both Rome and Korea. These times had never been approached before but after 1991 with the new track surfaces they became more common with some times under 3.80 but many times at or around it in recent years.

While talking about the results Ben ran in 30m…how fast did he run 30m from a standing start (in training) HT?
Thanks
He ran 40y in 3.7 so you can guess (3.1?)
I believe oxygen concentration [breathable gases] decreases with humidity because the very same volume is filled with “gasified water” and there is less space for “air” molecules, BUT volume density of the gas you breathe increases because in the very same unit there are heavier molecules than before (moisture vs. gas). Oxygen / nitrogen and other atmosphere gases rise to give place to heavier H20 molecules. That way the atmosphere becomes more viscosius and it requires bigger forces to move arround in it.
Am I wrong?

Check out this poorly made graph, its bolt 09 vs bolt 08. The difference is really from 60-100m, do you think if he didnt ease down he could have run that in beijing?
It is interesting to note that both Gay and Powell ran the same times at 40m, 50m, 60m marks;
40m - 4.70
50m - 5.55
60m - 6.39
Powell was ahead of Gay at 20m, and 30m. The biggest drop in AP performance was at 80m mark.

Some old posts (2006) on the same subject.
This list has undergone dramatic change as I have included split-times from Gatlin’s 9.77=WR in Doha earlier this year. Kim Collins’ 1.67 0-10m Minus RT is taken away as it was an estimate split-time that I gave for him in my 2004 Athens OG 100m Final Analysis
Also, with the inclusion of Gatlin’s new best time of 0.85 from 30-40m Mo Greene & Asafa lose their shares of the best split in that section

it’s really a bit pointless because the timing is in the 'eyes of the beholder" and i allowed the athlete to “commit” to an aggressive motion. I did this because I wanted the athletes to lean into the run before the clock started to encourage relaxation. A stricter timing means would quickly show the athlete that changing to a more abrupt start would yield better times over the short stuff and encourage tightness.
As long as I was consistent I could predict a block start E-time from there but others might get a much slower hand time.
In general, I would add .65 to equal an E-timed, block start over the distance, including the reaction time. That seemed to work pretty consistently for me and that’s why we were able to predict race times as often as we did.
I should have formulated my question differently. I was looking for this info;
In general, I would add .65 to equal an E-timed, block start over the distance, including the reaction time.
Thanks.
I wonder if AP entrained a “slow down” response by shutting down all the time.
no but he tends to power more than Bolt or Gay at top end and this track prob is not very forgiving.
How does Gay go from 0.85 to 0.84?
I’ve seen mention of micro-accelerations and decelerations within splits. Maybe the slightest change in stride, pushoff, etc., affected a minute change within a mini-split - say 77 meters to 79 or something - and made two .84s (or - the speed required for .84) slightly unequal.
Subject: Gay 0.85-0.84 over last 20m
What I think has happened (because we do not have the 10m splits) - I have done some maths myself - here is that 80-100m was done in 1.69. It is an odd number and when divided by 2 we get 0.845.
If we try to work out the times from 100m to 90m and then 80m, whoever did this must have rounded 0.845 to 0.85 therefore you get;
0.84
0.85
In reality (this yet needs to be officially confirmed) it could have easily been that Gay ran 0.84 and then during the last 10m split 0.85 if one was to work out the times from 80 to 90 and then 100m. I tend to believe it was 0.84 and then 0.85…
