I know that if you purchase too many Typhon abilities, you will be counted as alien by various Talos-1 systems like the turrets. And there is icon indicating how much you are transformed towards that.
I've purchased 2 abilities at a cost of 3 and 2 neuromods each. This caused the icon to fill to half. I concluded that I will be counted as an alien after purchasing either 2 more abilities or spending 4 more neuromods on typhon abilities. Yet after purchasing a single 2 neuromod cost ability I am getting a full icon.
I've also purchased few abilities from "Scientist" branch, for increased Psi capacity and for additional chips for Psychoscope, but I doubt those are counted as typhon abilities.
So, how is this actually counted? Or is the indicator not really indicating the exact process of transformation?
