The 48-year-old identified a key error that both judges failed to spot during Sunday night's results show.
Shayne, 40, and Nancy Xu, 33, were voted out of the competition after performing their rumba to Cyndi Lauper's Time After Time Again.
They were in the dance-off against Wynne, 52, and Katya Jones, 35, who were saved after dancing their American smooth to Mika's Grace Kelly for a second time.

Speaking exclusively to on behalf of , the professional dancer suggested that timing is a major element in scoring the show's competitors.
"It was a very close dance-off, so it's not that far-fetched that they saved him [Wynne Evans]," Brendan explained.

The judges' verdicts were split. and backed Shayne and Nancy, while backed Wynne and Katya.
It was down to Shirley to cast the deciding vote, and she chose to save Wynne and Katya, saying: "One of you displayed more of a powerful and joyous routine for me - so it was quite difficult for me to choose, but on this occasion, I'm going to save Wynne and Katya."
Disgruntled fans shared their disappointment over Shirley's decision, with some viewers going so far as to call a petition to remove the head judge from the programme.
Shirley was slammed earlier this month after fans of the BBC show revealed that they believed Sam Quek, who was sent home last week, was underscored by the judges.

The judge said: "The show's been on over 20 years. The public vote makes a difference."
