battlelog stats totally out of sync

my vehicle battlelog strats are totally out of syncronization with the ingame stats.

it happened in early december after a battlelog update (i think is was battlellogupdate on novembre 1st). since then, i ve been opening threads over threads over threads to maybe get an answer by ea/dice, because this sucks.



example:
anti air: battlelog ( 55 stars / 66%) vs ingame (72 stars / 31%)
jet: battlelog (34 stars / 51%) vs ingame (39 stars / 74%)
etcetc.
how is that possible?

it is the same with every vehicle. so whats the deal? how can that be that out of sync?
what can i do, to fix it? i dont care, if i have more or less service stars either ingame or battlellog, but it should be the damn same number because this makes me mad.

i am very often playing in a session one whole service star of anything, but this doesnt work anymore. i wanna do a "whole" thing, but it is never a whole thing, because either ingame or battlelog is wrong.
