Haha, I don't know if Hamilton meant that or not, the little comment about can always improve. Last week Rosberg kept on with the, it was 4/100th's, kept saying he would win but for 4/100th's and that there is always more time in the lap. I felt like Hamilton might be adding a little to say, yeah, I could have gone even faster myself. The irritating thing with Rosberg was his insistence he'd have won had he gotten pole... off the guy who utterly controlled him in every session including the race. Hamilton could have started 5th last race and he'd have won.
I did say last week though, you can't go too easy in Q2 because you have to have some idea of where the limit is from Q2 to feel your way to a great lap in Q3. I mean, Rosberg was pretty much making an excuse for himself, he'd never have been close to Hamilton but had he gone a bit faster in Q2 he'd likely have had the confidence to push a bit more on one/two corners and maybe get second.
