Hmm.
A 1-2 in the first race at Pau, a win in the 3rd race. 2nd and 3rd in the first race at Hungary, Schumacher on the podium in the 3rd race. Norisring - Armstrong wins the first race, places 2nd and 3rd in the other two. Zandvoort - a 1-2-3 for Prema in the first race. Spa - a podium for Zhou in the first race, Prema cars 1-2-3 in the 3rd.
You and I clearly have a different idea about what would constitute a car being "a dog for the first half" of the season. Because it seems to me like the Prema team has competitive all year long. Is this another of those situations like "nurr MotoGP breaks the lap record at every race, also so does Moto2 and Moto3 nurr"
Note for everyone else - deuse won't see this, because he has me on ignore.
