Mark Webber has summed up Sunday's Chinese GP saying that it was exciting but difficult, at least in terms of strategy.
Pirelli's tyres played perhaps the most important role yet this season in Shanghai with the top ten split evenly over two or three-stoppers.
Race winner Nico Rosberg opted for a two-stopper and clinched the win by 20.6s over Jenson Button with Lewis Hamilton and Mark Webber also opting for three-stoppers.
Although the three stops meant the trio spent more time in the pits and working their way through the field, it also meant that they had fresher tyres when it came the final five laps.
And that fresher rubber gave them the grip needed to overtake the two-stoppers ahead of them, including reigning World Champ Sebastian Vettel.
"It was a pretty difficult place to work out the strategy," Webber told the BBC.
"We lost some positions at the start as we struggled to get the tyres working and I had a poor getaway.
"But I got my head down and tried to execute a slightly different strategy.
"In the end, fourth is probably not the maximum, but after I made a few mistakes running wide trying to push.
"It was an interesting race, enjoyed most of it."
He added: "It was different strategies playing against each other - utter chaos.
"The difference between fourth and fifth is not massive between team-mates, it was just a few more points that was all.
"We've finished close to McLaren in all three races but there's a long way to go."
And like many of his rivals, Webber took the time to congratulate Rosberg on his maiden victory.
"Congrats to Nico. That's the big news story. He deserves the victory."
