I still didn't understood, on what basis, he has calculated fuel loads. If you are following Mercedes, you would know that they are the only team to be pushing the tyres extremely hard at the beginning of every stint to understand the wear rate. So, obviously the degradation is very high and then if you read, post testing comments from Brawn and Haug, they don't think they have a degradation problem.
Nico set fastest lap time on a stint of 15 laps. This is atleast one indication that they have been testing with heavy fuel, whereas all other teams did their best times on 1-5 laps.
Well, only Melbourne Q3 will give a real picture.
