The number of my kills and deaths are different between way point and career in multiplayer in mcc? Which one is correct?

Yeah me too, I think it is because when mcc launche a lot of kills were not registered in career, and halo 3 never registered until april-may. Or maybe this is because on waypoint it is glitched.
Career is more likely to have the true count anyway (just halo 3 kills are missing from november to april-may).
