Lewis Hamilton says he and Mercedes have been looking into starts "every single day" in a bid to solve the team's recent struggles off the line.
Hamilton won in Canada despite a slow start which saw both Mercedes drivers jumped by Ferrari's Sebastian Vettel into Turn 1. Starts have been an ongoing area of concern this season for Hamilton, who admits the team is still trying to find the perfect solution.
"We look into it every single day," he said. "It's a conscious thing, I've got constant goalposts that are moving, but the last one wasn't great, it was second to last worst. But then in China I had the best of the whole pack, so out of the seven races and five or six starts -- whatever it is -- there's been one fantastic one and then a few not so good.
"So it's really just moving around and trying to narrow that performance window because it's too far different between the spectrum. So we're trying to make that more consistent, for sure."
Hamilton's back-to-back wins in Monaco and Canada halted the momentum of Mercedes teammate Nico Rosberg, who had won seven in a row before the pair collided in Spain. Momentum has swung back and forth between the Mercedes drivers since the start of its dominance in 2014 and Hamilton thinks that is proof the team has two talented drivers on its books.
"I don't know why that would be. For me that says we're both pretty good drivers I would say. I don't have a reason for it but I don't think it really means anything. It might be a set-up thing when you find the window of the set-up of the car and sometimes there's a couple of races where the balance and the set-up is very similar.
"If you're a little bit - a couple of percent off - with the set-up, it's time lost maybe. I don't know. Then you arrive at another track and it changes again maybe. For example here it's a very similar set-up to the last race. Then we can go to another one and it might be a lot different, so I'll find out tomorrow if it's the same."
