Would have to disagree. All the Mercedes powered teams had a positive point differential between 2013 & 2014 (Mercedes +341 (94% inc), Williams +315 (6300% inc), Force India +78 (101% inc) and McLaren +59 (48% inc)). Everyone but the Marussia and Caterham (+2 (0 to 2) & 0 (o to 0) respectively), were in the negative.
