Yeah... nice find! Since it's not possible to extract data from game... maybe he tried every combination possible with his friend(s) in custom game, very dedicated research. Those damage values against every kind of armor can be added to infoboxes. DPS and STK (shots to kill) are unnecessary imo. Also, there are more than 5 different range values to feature different damage, so... maybe it will be okay to just put "Damage falloff" range instead of doing all of them with armor multiplier in mind.
