The victory also saw Winx emulate Tie The Knot's four consecutive Chipping Norton Stakes wins which spanned from 1999 to 2002.
Waller described Winx's fourth win in the weight-for-age contest as "certainly no easy feat" but said a truly run race played in her favour.
"I've been around racing for more than 50 years, riding and training, I've watched thousands of races and I can tell when a jockey is kidding to them", Webster said.
'I know she has got another gear. another jockey might have panicked, but I knew when I balanced her up she would find the extra gear and she did it with relative ease in the end'.
"It's another race record here this afternoon", Bowman said.
"Blake, I knew Blake would try to pull a rabbit out of a hat".
With the win, Winx passed Hurricane Fly, the Irish Willie Mullins-trained horse who had won 22 Group 1 wins.
"She's always a bit edgy at the start of a prep and having to stand there for a while will do her the world of good", Waller said.
Asked about winning a 23rd Group One race, he replied: "She's a superstar, very, very special".
"It was a good test for her and it will bring her on nicely for her next couple of runs".
Happy Clapper jockey Blake Shinn could do little but applaud.
"What can I say about my horse?" he said. I didn't expect him to do it that way.
The $5 million All-Star Mile is next on the agenda for Happy Clapper but Webster is hopeful his gallant effort in the Chipping Norton won't leave him battered and bruised.
"She's just a freak and she had to put up a freakish performance to beat Happy Clapper". We got a glimpse of it with Black Caviar, of course, your Makybe Diva's and now Winx following on from that.
