Exactly, only at the start of the Australien GP will show everybodies real pace, Barcelona Testing might give an indication but doesn't tell much either (at least not the laptimes)
of course it will be a hard fight for Gasly but if he can bring the fight to Verstappen, Verstappen needs to up his game aswell, which can be good for the championship fight, if the Honda gives what is been told.
(although i think Gasly ain't as good as Ricciardo is, and we all know how that ended)
