You're basing it on that when Ferrari up to Germany clearly had the fastest car but did not disappear out of sight like they should have
Had Ferrari built up that gap they did before the summer break I don't think Mercedes would have caught them last season
I guess this season you're going to be in denial that Ferrari is the fastest car and saying Mercedes is based on results ?
Wouldn't be more accurate assessment concluding that race outcome is more than ever before track topology and flawless race strategy dependent? When cars are finishing laps in fractions of a second apart, I am puzzled how anyone can be so sure which one is so unequivocally "faster". For example I do perceive Mercedes being more stable over Ferrari in turns, not that they loose anything on straights. Then toss into mix tarmac temperature and conditions of tires, and do you still want to claim that Ferrari is more competitive (faster) than Mercedes? It might be for all what I know, but being sure.…? For now, I doubt that. It's too early in the season to be "sure" of anything IMO. Cars are still sorting out changes imposed by FiA over winter. This may continue for a while. Mercedes was ahead of Ferrari in later part of 2018, and I think their 2019 development cycle started earlier than one in Maranelo. Merc is probably still ahead.
