Scenarios ordered from what made most sense to what made least sense:
1. Pit Oscar first, they retain the positions, and they are told they are free to fight as long as they're extremely careful
2. Pit Oscar first, they retain the positions, and they are told to hold station
3. Pit Lando first, they switch positions as we've seen, and they are told to hold station for the championship
4. Pit Lando first, they switch positions as we've seen, and they are told they are free to fight as long as they're extremely careful
5. Pit Lando first, they switch positions as we've seen, and they are told to switch back again
You can order scenarios 1 to 4 differently depending on your interpretation of what priorities the team should have, but 5 is clearly the worst. Congratulations McLaren, you've picked the clear 5th best option.
