I'm fairly sure it would have been planned out months back, each team working out how best to map out the season.
I`d say no because, you don't give them 5 engines at the start and they lock them, so if they find a fault or an upgrade they can do it for there remaining engines, now they having used 4 engines they can only modify the remaining one which limits them.
