I think what Ian is trying to say is that she is the fastest lady currently riding at the TT.
According to dukes database Sandra is the lady with the quickest ever lap by a female at 114.87, but its getting very close now, about 1 second in it. It is a sign of how good Sandra was that it is still 7 years later that her record still stands, not many records last that long.
The Manx Radio commentator said Maria was now the quickest, but he also said "French man Fabienne Migout had done well" ????????
Fabienne is of course a female rider.
Bet Geoff Cannell was P*****g himself, if he could stay awake long enough through the dulcate tones of this years commentators, apart from the one at Glen Helen, who was good as ever.
