I currently have 2 members in my party with the Electronics skill (Garrus and Liara), which, in addition to its other functions, also serves as the baseline for hull repair of the Mako. Every point in Electronics increases the amount of hull repaired by 200.
If I have both of them in my party, whose skill is used? Will the game automatically choose the highest Electronics skill in my party? Will (and I highly doubt this, but I'm wondering for completion's sake) the amount repaired stack?
