t3-m4's defensive penetration zeta

So there is a lot of debate about whether or not T3-M4's defense penetration zeta adds an ignore all armor/resistance to droids, or if it just adds 100% of his defense pen to droids.

I purport it adds 100% defense pen to droids as opposed to adding his amount of defense pen to droids. Here is the defense to my position.

To begin with let's start with the ability mechanics of T3-M4's Combat Logic Upgrade according to swgoh.gg:

For All from Ally Side who are Alive and is species_droid
Modify stat Armor Penetration by 100% * CONTEXT_VALUE (additive)

In comparison.let's look at CLS, and Kanaan.
--------------------------------------------------------------

C
For Self who is Alive
Modify stat Tenacity by 100% (additive)

-----------------------------------
Kanaan gains double tenacity:

For Self who is Alive
Where an active effect has tagspecialability_kananjarruss301_taunt
Modify stat Tenacity by 100% (multiplicative)

-------------------------------------------------
So according to swgoh.gg, doubling effects are multiplicative, and flat % increases are additive, and this is additive.

If anyone could confirm or deny this, it would be great!
