Yates does not carry a calculator, but he will be doing the math when he is racing. Davide Formolo was third, five seconds behind Yates.
By the time the 28-year-old Colombian crossed the line in the gruppetto, the counter was north of 25 minutes, ending any hope of Mitchelton-Scott completing an historic one-two in Rome - but ensuring that all eggs will now be put in the basket marked Yates.
He won his second stage and celebrated his second victory in four days in the pink leader's jersey.
On a bittersweet - but predominantly bitter - day for Mitchelton-Scott in Le Marche, race leader Simon Yates picked up a few intermediate sprint bonus seconds to strengthen his grip on the pink jersey as team-mate Chaves cracked on the first of three categorised climbs to finish more than 25 minutes down on stage victor Mohoric.
But there is Tom Dumoulin. He underscored his intentions to win a second consecutive Giro.
It was another hard day for reigning Tour de France and Vuelta a España champion Chris Froome, with the Briton losing another 40 seconds. I first thought Esteban Chaves would be able to come back but it was a really insane stage and I'm very disappointed for him as I know he's worked very hard for this.
Dumoulin does not know how much he could gain - or at least he would not make a prediction. "I felt good all day and I'm really pleased that I took advantage of the opportunity".
"I never look at time differences, I just go full-gas until the finish of the time trial and I will see what I get".
There is, of course, the small matter of a brutal weekend doubleheader in Friuli to negotiate first.
"We saw with Esteban Chaves how quickly things can change for the general classification riders, so we just have to keep plugging away and keep trying to do everything we can", Froome said. Finally we hear from Sk's sports director Nicolas Portal about another bad day for Tour de France and Vuelta a Espana champion Chris Froome.
"It's not a two-way battle, because there are four to five guys who are still close". "The time trial - I'm afraid of it, let's not dodge that question", Yates said.
