You can always improve your fitness if you keep training.
I think in my car somebody is playing with the pressure and the temperatures.
That was a frustrating race for me. I pushed as hard as possible at the start on the medium tyres whilst everyone around me was on the grippier soft compound rubber. Once I moved to the soft tyres I was able to set the race's then fastest lap so things looked good with our strategy. Unfortunately the engine anti-kill triggered when I came in to make my final pit stop which cost me a lot of time. It's frustrating as we should have finished strongly. My focus is now Barcelona where I've delivered very strongly in the past.
