Michael Johnson is "extremely confident" his work with the Williams team to improve their pit stop times will make the difference this season.
Earlier this month, Williams announced that they had brought in the sprinter's Michael Johnson Performance Inc to help their pit crew shave vital hundredths and even tenths of a second from their pit stop times.
And although the more cynical wondered if this was nothing but a fantastic marketing gimmick, Johnson is confident the proof will be in the pit stops come March's season-opener in Australia.
"I feel extremely confident in myself and my staff in terms of what we have put together in training methodology and biomechanical efficiency,"
Johnson, a four-times winner of Olympic gold, told The Guardian.
"I don't think anybody knows it better than us.
"There is a tremendous amount of biomechanical movement going on in the pit stops so it stands to reason we can make that quicker.
"The amount of steps that it is going to take for the guy that has got that tyre and has got to put it on - it makes all the difference in the world which is his lead leg to how many steps he is going to take.
"And the guy with the gun - it jumped out at me immediately that you can do it two different ways. You can take it off the wheel and bring it straight back into your chest or you can take it off and point it upwards to get it out of the way.
"What has never been done is to evaluate the guy from a sensory stand-point to see how accurate can he be."
Asked how long he'll be working with Williams for, Johnson said: "We'll be going until it gets done."
As for the crew from Williams, Ben Howard, the man who works on the left front wheel, said: "I think everybody was excited, but possibly a little bit apprehensive as well.
"Michael is well known and trains top-level sports people but we're not professional athletes so there was some nervousness as to what he might make us do.
"To be honest not everyone goes to the gym to train because we use our own activities and hobbies outside of work to keep fit. It's been good, though, really interesting, and obviously a privilege to be working with someone of his calibre."
