Starting from 19th place with a full tank and finishing sixth is obviously a lot better than I expected, so it was a very good race for me. The only problem I had was warming up the tires after the numerous safety car phases. We have to have a look at this to improve the situation but otherwise our pace was good.
Normally the good teams stay in front when there is a regulation change, the teams that do the most testing and have the most budget end up adapting fastest. From pre-Christmas testing it's very difficult to know because not every team was running with V8s, so it's really impossible to know where anybody stands at the moment.
I had to back off on one lap near the end because of yellow flags, but that happened while we were on a long run so it wasn't really a problem and I did my best lap on the next one, which was my last. The grip was getting better all day, having been very low to begin with this morning. We still have some set-up work to do, but it was okay.
