Tonight I was flying bishop (my squad flies free agent for whatever side needs us or seems to)
At one point only 3 people were on bishop in the MA, myself, my wingman and one other guy.
I so I dropped a 1k bomb on a tiger from my p38 for 1 kill, landed for 120.41 perks
 Then I took off in a 109G6 and quickly dispatched an La7 for 160.00 perks
 Then a few more missions for lesser bonuses.  
Meanwhile my wingman reported a single La7 kill for 178 perks
and a base capture in an m3 for a whopping 199 vehicle perks.  But the handsomehunk didn't take screenshots.
Is this kind of multiplication of perks intended?
