So Far i have noticed the Yak-9t cannons will always give you an assist if you kill a fighter that even the slightest damage.
In the DA i was flying a yak-9t and i saw a spittie with a fuel tank leak. (not on fire) so i used 3 cannon rounds and shot its wing off, it hit the ocean, and i got an assist. this happened 4 times that sortie. i was out of ammo with 2 kills and 4 assist( all of the assist were when they were slightly damaged)
so I am saying when hit an enemy FIGHTER with a 37mm (which is always fatal),you get an automatic kill, unless, of course the fighter is missing a critical part (i.e: the wing, tail,etc) I love flying the yak but the system unfairly gives the kills to people who put more rounds into it, but didn't do critical damage.
so 37mm into enemy fighter with no critical damage = kill.
