You have to give them a break here, The race did not take its course, so plans would not have worked out anyway.
Yes, they possibly muffed up not pitting Lewis with Seb, but the lightning first lap was not expected.
Once they could see that it had been a mistake, there is no way they could undo it do had to go for a best option alternative.
Possibly Ferrari intended to stop again, or at least had it considered, but as the second half of the race fell into a farce, it was impossible to plan for. Track position is king, but once it was gone it was gone. The only reasonable alternative was a 'tyre fight' at the end.
A mistake yes, but not a complete ballsup, just circumstances.
We are standing on the shoulders of Giants. So watch your feet.
