How did you start that thing. It looks like you did a falling start. Did you?

i didnt mean to if i did

No thats cool I was just asking. I think people might have mistaken that the jogging in the first part of the tape was your actual 40. I did. Doesnt look bad. Where is that at your house?

knees looked low, was hard to tell. Are you able to reproduce it in a slow mo version - without the jog to the start line?
Also, see if you can use the lawnmower to cut a Running strip , and place some lines to follow or hats, it appeared as if you went off line?
Also, it makes it hard to see when your wearing baggy shorts.

Just some ideas that might make it easier to gauge your technique.
