I was going to ask about that. Any good news, like insurance, work replacement, credit card lost/stolen coverage, etc.?

Filed a claim but I don't think I'll get total value ... Computer was only about 6 months old, but the technology has changed so much that in the end I will end up upgrading so I guess that is a good thing ...

As long as you get a decent chunk of it back, that at least lessens the sting. Can you write off the purchase(s) and loss on taxes, since it's work related and I assume you paid for it yourself?

Hadn't thought about that ... And yes it was my own purchase ... I use a computer far too much not to have it belong to me ... But hey ... This time around I'll go around 2GHZ, 40GB, 15" and do it right !!!

re-Greene at 60m in Maebashi, IAAF webpage doesn't give any 50m splits for Maebashi. The 5.59 is listed for Greene en-route to his 6.49 win in Madrid (Madrid and Liévin use to give 50m splits nearly every year, Mardid didn't have split time system during Greene's WR 6.39 in 1998 though).


Sorry.I must of been dreaming!
Thankyou PJ. Embarassed

Adding 20m split times would be fair, because 10m splits with 0.01 accuracy aren't that reliable.
For example if you take splits as 5.610 for 50m and 6.450, the 10m section is 0.840, but if an other athlete does 5.602 and 6.450, the split is 0.848, but rounded-up to 0.84, as 5.602 is corrected at 5.61. So i'm not sure we can add such unreliable data. Taking 20m splits would delete a little those inaccuracy (even though i think 0.01 accuracy is enough to search 10m splits, as it is worth 10cm, which represents the torso/shoulder twist during sprinting).


20m Splits is harder than 10m Splits for some reason which I cannot explain!!! I tried to do more complicated Splits.E.g 0-20m,10-30m,20-40m etc. But I have had a go at the more 'simple' Split collecting, and I have found some very interesting Results from the data.

Men
RT Limit: 0.100s
0-20m:(Minus RT) 2.70s Maurice Greene(USA) Edmonton WCh 2001
20-40m:1.76s Maurice Greene(USA) 1999
40-60m:1.66s Maurice Greene(USA) Roma GP 1999 and Sydney OG 2000
60-80m:1.66s Maurice Greene(USA) 2000
80-100m:1.70s Maurice Greene(USA) Athens GP 1999

Total:9.48s
Total+RT Limit:9.58s
As you can see the Total of MO's Best Times is only 0.01s off of his Best Total for 10m Splits of a 100m race. This indicates that MO achieved his Best 10m Splits in no less than 7 races.
I am still working on a list for Women,this will take time as I haven't as much Data on Women as I have for Men. And I don't won't to be accused of giving innacurate and 'false' data. I think that PJ will have something to say about that last comment!! Laughing
And the lists of Marion Jones' and Flo-Jos' Best 10m Splits compiled,I am also working on! I have come up with a list for Mark Lewis-Francis who is still young and has plenty of time to amend his Attitude and Performance,and I can see that I will be changing his lists almost on a weekly-basis if he carries on improving like he did in 2002!!!!!
But as I am posting from a relatives' computer in their house.I cannot obtain my Data on MLF. So I shall probably post that data when I get my act together on the lists of both MoJo and Flo-Jo!!!
Very Happy

Could you explain where that last part comes from? It isn't clear from the data you just posted how the 7 race figure is derived, but maybe the underlying 10m data is the key?

Sorry, I wasn't very clear on that! Embarassed I did mean the underlying 10m data.That was the key to what I was saying. I meant that Greene made his Best 20m Splits in 6 races, Edmonton WCh 2001,cannot recall the race,but it was in 1999, Roma GP 1999 ,Sydney OG 2000, Berlin GP 2000 and Athens GP 1999 .And the further race which made up his 10m data was a race which I also cannot recall,in 1999.
I hope that what I have just said is more clear than my previous post to this topic. Very Happy

Ok, I think I follow. Basically what you're saying is that 6-7 races account for all his best splits no matter how you compile them, thus indicating consistency (at a high level) throughout each of those top races?

That would only stand to reason ... You can't have races at the top end of the scale WIHTOUT having put together a string of outstanding "interim splits" along the way ... Inferior splits would have lead to an inferior time ... Sub 9.80 races by their very nature are going to have a string of outstanding incremental sections ... Same for 19.7x (and better) 200s ... The best races wouldn't be that under any other circumstances !!!

That is Very true Conway.You cannot have your Fastest race and not put together some of your Best Ever Splits en-route. E.g Bruny Surin Sevilla WCh 1999. 2nd,9.84s(=ComR & NR) He made his best en-route Splits for 0-10m,10-20m,20-30m,30-40m,40-50m,50-60m,60-70m,70-80m & 80-90m Splits.Which pretty much gave him his 'Perfect Race'.
And of course Ben Johnson in Seoul OG 1988.He had his Best Splits for 0-90m in that race!!! It was only his last 10m Split of 0.90s which lost him 0.04s compared to his Best Ever Last 10m of a 100m (0.86s)
If he had run that last Split he would of ran 9.75s!!!!!(8.89+0.86)
MO done it in Edmonton until he got injured in the final 15-20m of that classic race.Tim Montgo done it Oslo(9.84s),Edmonton(9.85s) and Paris(9.78WR) So your comment is Very-True,and applies to most Athletes who have had their Best Ever race. Smile

Originally posted by Charlie Francis in his Communtiy Forums.
He posted a set of theoretical split times for the 9.65s that Dwain Chambers said that he would run.

RT:0.12s
10m:1.81s(1.69s)
20m:2.85s(1.03s)
30m:3.77s(0.92s)
40m:4.63s(0.86s)
50m:5.47s(0.84s)
60m:6.30s(0.83s)
70m:7.12s(0.82s)
80m:7.95s(0.83s)
90m:8.79s(0.84s)
100m:9.65s(0.86s)

10m Split:0.82s, 60-70m.
50m Splits:5.47s/4.18s =9.65s.

That's what Chamber's 10m segments will have to look like if he wants to achieve such a time.
And if we look at his current Best 10m Splits from various 100m races in which he has competed in, we see that he will have to RUN to get that kind of time.

Dwain Chambers(GBR) d.o.b:05.04.1978
(The Splits come from various Videos that range from 25-120Hz in speed of frames/s)RT Limit:0.100s
10m:(Minus RT) 1.71s('02) (With RT) 1.84s('9Cool
20m:1.01s('02)
30m:0.92s('99 & '02)
40m:0.89s('02)
50m:0.86s('99 & '02)
60m:0.84s('99 & '02)
70m:0.85s('00 & '02)
80m:0.86s('02)
90m:0.87s('02)
100m:0.88s('02)
Total:9.69s(!)
Total+RT Limit:9.79s(!)

As you can see his total without added RT Limit is +0.04s over what he predicts from a block start with added RT.
Below I have included a +/- list of his race Splits ompared to the theoretical Splits drwan up by Charlie Francis.

+/-: 'Race Splits' / Theoretical Splits
10m:(With RT)+0.03s/-0.03s
20m:-0.02s/+0.02s
30m:+0.00s/+0.00s
40m:+0.03s/-0.03s
50m:+0.02s/-0.02s
60m:+0.01s/-0.01s
70m:+0.03s/-0.03s
80m:+0.03s/-0.03s
90m:+0.03s/-0.03s
100m:+0.02s/-0.02s


Chambers, Chambers, Chambers...

Gee, he only needs to hit the first 10m 0.15 seconds faster... Maybe if he loses 40 pounds, but it's not happening otherwise. Exherting the effort necessary to pull off that kind of acceleration improvement is bound to screw up the rest of his race.
