Is Aiming Overcharge Additive o Multiplicative?

So, having ourchased the Lynx MK2, I outfitted it with the Gauss Cannons. I saw he aiming overcharge module. What  would like to know if the increase is additive or multiplicative. For example, if my primary weapon’s crit chance is 7%, is it increased to 36.7% (increased by 29.7%) or is it increased to 9.079 ( a 2.079% increase)?

+36,7% not *

so your crit chance is 36.7% while active 

+36,7% not *

so your crit chance is 36.7% while active 

Thanks!

beware that gauss charges have different critical hit chance values (first charge is 1x, second is 2x and third has 3x crit chance). Also the gun automatically charges to the second charge when you stop firing for a short while.
