Not this year. Before this year undoubtedly so.
As for a masterstroke with regards to three stop strategy, you miss a very important point. That strategy put them in a position they were after the safety car. The only car on the track, which ultimately costed them the podium. So how on earth could it be the right one? Just unlucky? Just wrong.
And even If they knew they could only fit hard in case of late SC, then why stop for the 3rd stop (to put on not even new but used soft!) as early as lap 47 out of 66 ? Max spent 17 laps on brand new medium and was supposed to somehow put Mclaren under pressure having to drive 19 laps stint on 3 laps used soft?
Not only Piastri was already too far, even Norris was 4.5s ahead and could not be really put at danger of undercut.
It was a pure gamble. Like lets stop now and hope Mclaren do 4s stop, and hope Max could be able to hang on for 19 laps. How often do Mclaren make such poor stops anyway?
They refused to take an easy chance to undercut the Championship leader in Monaco to take P3 and now gambled trying to force near impossible undercut in Spain? makes very little sense. No, they do not operate like the best team on the track this year. They operate like gamlbers hoping for miracles, rather than a team truly fighting for this championship.
I don't think three stopper was better, faster strategy, although it made the race look somewhat entertaining for a while indeed. Otherwise it would've been dead boring, although Max would've taken his prize for 3rd.
