Valentino Rossi salvaged sixth place from just 13th on the grid in Sunday's wet British MotoGP at Silverstone.
But with Ducati team-mate Nicky Hayden setting the fastest lap of the race - 2.989sec quicker than Rossi - on his way to fourth place, it was clear that the Italian hadn't got the best out of his Desmosedici.
Rossi had been on the back foot ever since the start of the weekend, his first at Silverstone having been missed last year's event due to injury, and The Doctor accepted his share of responsibility.
“Without a doubt, this weekend was the most difficult so far this season, but we at least managed to do a good job of limiting the damage," began Rossi. "Considering how we came into the race, sixth place is a fairly positive result that helps us to stay not too far from the top of the standings in fourth, which isn't bad.
"We knew that my lack of experience here compared to the others would hurt us, but it's also true that we haven't managed to improve our setup as well as we should have. In fact, today Nicky managed to have a nice race and ride well, even setting the fastest lap, which demonstrates that the Ducati is competitive in the wet.
"We didn't improve enough though, and that made it hard for me, as the bike was difficult to ride and I couldn't push hard. We're all responsible - me, the bike, and the team - so together we'll try to improve and return to the level we were at in Le Mans and Catalunya as soon as possible, and then take another step forward.”
Rossi finished 37 seconds behind Hayden and over one-minute from race winner Casey Stoner (Honda).
“Unfortunately Valentino never managed to find a good feeling," added team manager Vittoriano Guareschi. "We must figure out why that was the case at this particular grand prix, then return to the positive trend of improvements that we had been on since the first race.”
