They had already set this target before the season started, when the total races were still 22, so in a way I'm not surprised they're still targeting it now that 17 races have been confirmed with almost the same amount of components.
In a way I'm disappointed though. Being that Verstappen is 47 points down from Hamilton, why not unleash more power and use one more ICE, TC and MGU-H?
The only reasons I can think of is that they are quite confident with their level of power output. But even then, isn't the penalty for starting at the back of the grid in one race well worth the benefit of running more power output for the remaining 10 races?
This is just my theory, as I believe that going all out is the only chance they have of still making Verstappen the youngest WDC in history.
But surely, they must know something that I don't or am completely missing.
