Hard carried to uprank in CS2

Gustav and I have been playing a string of Wingman matches, primarily on Vertigo. He is HARD carrying me thru this. Funny thing is that even though he routinely gets away with 3X my kills, I am the one who upranks the most.
I guess the Valve logic is that MortVader is the creat0r of Gustav, so he get's the most of the XP every time? :D Kind of pwnage by inverted heritage!
