When I checked my score I noticed that under vehicles vs objects, Hit % is 0 but I have killed FH's, BH's, VH's, fuel, ammo, troops and even town buildings.  What needs to be hit for this to be calculated?  I noticed alot of people have 0% there.  
Another ? is why do we have a ranking for field captures under attack for bombers?  It will never happen as U can't have a C47 under attack mode.
