The home-page-linked article intrigued me. Did a Guyanese run sub-10 (and 20-flat) on grass? Then I read the article
There, Perry reportedly broke the 10-second barrier, and if the times are legitimate, ran the fastest ever 100m by a Guyanese athlete. According to the official results, Perry also clocked 20 seconds flat in the 200m. Those performances will not be accepted as Guyana’s national record because they were not achieved at an international meet where they would have technology in place to verify its validity. Guyana’s obsolete conditions, where the hand-timed system is still employed and where there is nothing in place to measure wind …..
Ah so, 9.9 NWI, is a lot different than a legal 9.99. That said, the Wimbledon grass would be great to sprint on!
note that he puts his hand through an eyebeam (so he has a rolling start) and there are no starting blocks (so there's no reaction time as part of the equation). So you need to add about 0.20 to the time.

More than just 0.20, I would think. Out of the blocks, it is 0.15 for the top sprinters when they get the first pressure, it is probably 0.25 before they have much momentum at all; although maybe not having blocks makes the start a little less explosive.

Given that it was a test/advertisement for a football cleat, and that Asafa appeared to be cruising, I'm guessing that it was 100 yards rather than 100 meters. That'd convert to about a 10.85 for 100m, which would be an warm-up stride for Asafa. I don't think that it ever specifically said the test distance in video, did it?
It's a commercial...end of story. If you really don't have too much of a life (like me) and you want to waste time analyzing this then check out the lines on the field that he runs past. I doubt if it was even 100 yards. But who cares? They never state the distance he ran.
