codex and weapon variants

obsessed and geeked out with bf 1..completed all primary weapon dog tags,so 100 kills min,main codex are done... going for elite codex and just completed 'Benet mercie'.500 kills and xp. but checked weapons stats on companian and actual kills are 574..loooked at others and variants on others like..elite selbstlader 1916,codex 28.. actual kills 212..elite smle mk 111,codex 4.. actual 245 (including lawerance of arabia)..

as i read through this... its geeky,but playing the game and like the idea of PTFO which includes map objectives,dog tags,codex etc.. and the 25000 xp comes in handy
