30m: 3.81 [0.92]
40m: 4.68 [0.87]

50m Split-times: 5.52 + 4.25
60m + 40m Split-times: 6.36 + 3.41

Tyson Gay [USA]
RT: 0.152 [0.16]
10m: 1.90 [1.73]
20m: 2.93 [1.03]
30m: 3.87 [0.94]
40m: 4.75 [0.88]
50m: 5.61 [0.86]
60m: 6.46 [0.85]
70m: 7.30 [0.84] Fastest 10m Split-time
80m: 8.14 [0.84] Fastest 10m Split-time
90m: 8.99 [0.85]
100m: 9.84 [0.85]
50m Split-times: 5.61 + 4.23
60m + 40m Split-times: 6.46 + 3.38

Things to say:
Powell’s final 20m are the ‘slowest’ outta his 3 9.77s [Athens was 1.70 with 0.85 + 0.85 and Gateshead was 1.71 with 0.85 + 0.86]

Powell’s interval-times from 30-90m are simply awesome. He equals his Fastest 10m interval best at 30m, 40m & 90m and establishes new Fastest interval times for 50m, 60m, 70m & 80m

*Powell’s 5.52 at 50m is only behind Ben [9.79], Mo [9.82] & Fasuba [9.85] 5.50
*Powell’s 6.36 at 60m is only behind Ben [9.79] & Mo [9.82] 6.33, and also behind Fasuba [9.85] 6.35
*Powell’s 7.20 at 70m is only behind Mo [9.82] 7.16, Ben [9.79] 7.17 & equal with Fasuba’s 7.21 [9.85]
*Powell’s 8.05 at 80m is only behind Ben [9.79] & Mo [9.82] 8.02

With a 1.70 fastest finish for 80-100m, Powell woulda done 9.75, which is perfectly forseeable for him to do in the next year or so

Tyson’s first 20m weren’t so bad, but from 30-60m Powell does the damage to him that Gay only manages to cut into from 70-100m

Gay’s final 50m & 60m of 4.23 & 3.38 are amongst the Fastest EVER seen. Gat’s 9.77 finished with 4.22 & 3.38, Powell’s Athens 9.77 finished with 4.23 & 3.38, Greene’s Athens 9.79 finished with 4.22 & 3.39, Bailey’s ATL 9.84 finished with 4.25 & 3.42 and Lewis’ Tokyo 9.86 finished with 4.25 & 3.40 to name the Fastest finishers in history

Interesting info. Question…should the final represented 60m calcs, as highlighted, actually be 40m?

Yea, I caught that one too, I guess He means splits after 50m and 60m, he probably left out a word or two because the way it is phrased right now would seem like he means 60m splits.

My bad that was supposed to be the final 50m & 40m [I was thinking of the final 40m being from 60m]

Neverthless if Powell were to combine his Fastest splits from ALL his 9.77s [Athens 9.77 analysed by PJ & Gateshead + Zurich 9.77 analysed by myself] he would have:

00-10m: 1.86
10-20m: 1.02 [2.88]
20-30m: 0.92 [3.80]
30-40m: 0.86 [4.66]
40-50m: 0.84 [5.50]
50-60m: 0.84 [6.34]
60-70m: 0.84 [7.18]
70-80m: 0.84 [8.02]
80-90m: 0.85 [8.87]
90-100m: 0.85 [9.72]

For Powell to run 9.72 he would have to hold his best speed for longer, which would be achieved if he was to have a MAX +2.0 wind [or close to it] + great start + fast track + 100% fit. He’s not that far off …

This might be a stupid question, but, I notice the best 40m to start the race is 4.66, how do you have so many people that run 4.4 and better?

Thats 40 meters, instead of 40 yards. Also when people run 40’s thats minus the reaction time. But that is a valid point. 40’s are over-rated.

I think Charlie would agree that if sprinters tried to run a fast 40, they would, but they aren’t trying to reach top speed at 40 yards.

Powell’s 40 m time = 4.66 - .148 (RT) = 4.512
30m-40m time = 0.86 seconds/10 meters = .086seconds/meter

There are 36.576m in 40 yards, so the extra 6.576 meters * 0.08seconds/meter = 0.565536 seconds

For an estimated 4.3655 40-yard, with blocks of course, but without trying to hit top speed then.

That’s also eletric timing. At the combines where they use “eletric” timing, they still have a manual start from first movement, so you can add at least .1 onto those runs at the combine and possibly more if they go by anything that breaks the laser as opposed to the chest.

Give me a break!! Sprinters are going through the 40y much faster than in football. Ben ran a HT first motion 40y in 3.7. Desai ran 3.9 and I was just told by an S and C coach client that Justin Gatlin ran 3.9 at a recent try-out. These runs are NOT timed the same way so you need to compare the football players to sprinters timed the same way.

I agree. What I was hoping to get across is that elite sprinters wouldnt’ want to hit top speed at the 40-m mark (maybe I am wrong here), whereas football players running the 40 want to be at top speed before the 40yd mark.

The quick breakdown was to show that without trying to run a fast 40, Asafa runs faster than most of the times out there.

What gets me is HS kids who claim to run 4.3s, yet run 10.8 in the 100m if they are lucky.

That makes sense, my son runs a supposed 4.3 hand timed on grass with cleats, and he’s hoping to run a 10.6 this year.

Still disagree. The sprinters are going 100% to 40y (and everywhere else on the way through. They can accelerate farther because they have more speed- simple as that.

My mind was made up when I read about Deion Sanders 4.29 sec 40 yard electronic.
His best ever 100m was 10.29sec.

Therefor the fastest Olympic sprinters would do better than any NFL player in a 40 yard sprint.

I read Dwain Chambers did 4.18sec in European try-out.

Now Dwain was by no means at his all time fastest when he recorded that time.

What on earth might Ben have recorded in an electronic 40yd?, I’m bearing in mind there was daylight between him and other olympic sprinters allmost as soon as the 60 & 100m races begun.

Charlie, this being true, and using a similar technique to analyze 40 yd time for Ben, he would have run close around 4.32e (reaction time taken out), so why would there be a 0.5 second difference between your hand time and the estimate. Isnt that a bit high for hand time error? I have no doubt that sprinters will smoke football players in the 40, I just think the intent to run a fast 40 vs a fast 100 can influence the time, which might explain your fast hand time compared to the electronic estimate based on splits. Ben and Desai were trying to run a fast 40.

Not my hand times but a scout from the Dallas Cowboys who was looking at some football prospects.
The time diference from the athlete’s choice of when to move and a race forcing the timer to react, and a race where the gun fires starting the clock instantly, the athlete then reacting, etc, is enormous!
Average differential hand to Electronic is .24 plus the average reaction time both ways, adding time to the sprinter and subtracting it from the football player (R/T of .15 x 2 = .3). Put all together, you’re looking at .54 or possibly more.

Charlie, what type of differential would you use to convert from first movement to electronic? How were you able to tell back in the day how fast ben was running at 40m if you were able to tell at all?

Just throw this dog a bone or digit like .5, .6, .7 or whatever and ill use it, as long as it comes from ur mind with some sort of logic. I only have one person to time and train alone so he/thetimer don’t always come out. It would be greatly appreciated.

It all depends on the timer.

It really varies so much. Last meet, I paid extremely close attention to timing and never was more than .2 off, yet I have seen as much as .7 off even from myself if not paying attention. It’s all about the timers–without 100% attention to the race and you can pretty much guarantee there will be little accuracy.

I’m thinking it would be wise in the longrun to stagger the differential away from the .65 charlie uses. So for 50m use .75 differential from first movement to match electronic. For 40m use .85, and 30m use .95. And for the 60’s, 80’s and 100’s just use Charlies .65. However using differentials like this may strip away at the psyche of the sprintmindset, never the less the confidence.

If you are super worried use electric or at least don’t let the athlete(s) get overconfident from incorrect timing. Trust me, I know from experience handtimes really don’t mean crap w/o the electric to go with it.
