Golfer Melissa Reid says she has made huge progress after spending a year under Sir Clive Woodward's guidance.
Reid has her sights set on the professional Ladies European Tour
A BBC Sport survey has raised doubts about the impact Woodward has made as director of elite performance at the British Olympic Association.
But Reid feels his influence helped her finish as the top amateur at August's Women's British Open and to win the British Amateur Stroke Play title.
"I have improved massively since we have been working together," said Reid.
"More than I could have wished for."
BBC Sport has contacted 28 of the 35 Olympic sports and 18 said Woodward had made little impact in his first year as director of elite performance.
But the 20-year-old double English girls' champion Reid is of a different opinion after enjoying the benefits of the best medical support, technical advice and sports psychology.
I'm on the programme for another year and I hope it can continue after that
"I feel very honoured to have had this opportunity - it's a huge privilege," she said.
"I didn't know what hard work was until this all started. But I just look at it as an opportunity and I feel lucky that it was me.
"Until I met Clive I had a part-time job working at a Marriott Hotel to raise some money, but since becoming a full-time amateur my career has gone on to a whole new level.
"I used to go to the gym most days and practise for about five hours, hitting thousands of balls.
"There's a lot more that goes into it now. I'd never been a big fan of golf psychologists - I never really clicked with anyone - but the guy I've started working with has helped so much.
"He keeps it so simple and it's all about 'PUP' - performing under pressure.
"I speak to Clive quite a few times a week and see him once a month.
"I'm on the programme for another year and I hope it can continue after that."
Reid's ambition for the immediate future is to win a place on next season's professional Ladies European Tour - and that begins next week.
