since they are just scraping all the html info from battlelog wouldn't it be easier to just log into your battlelog account and view your information there? rather than allowing a third party to know your info...seems fishy to me. preying on premiums. i don't recommend using this. (Anon all over again)
Symthic collects the information direct from the game files, battle log just uses information which is in game featured. Example won't find the rocket speeds from the in game menu but can from Symthic.
Symthic also tests the recoil patterns using a random generation system
Not required to log into Symthic in order to gain access to this information at all and does not require your battlelog details
