Can you please advise how the damage stats are calculated?   Are they based on the symthic stats of the weapon vs. the damage that has been inflicted across the number of kills, or simply the actual damage being recorded by the weapon over time?

As an example the UMP-45 has a max damage of 30, if a player is showing 39 damage is this likely proof of a damage hack? 

Do these stats also take into account the reduced health of HC mode?

Thanks.
