I see the problem here. I think we're both right. When i did my post i was looking at Talos. If you look at the two companion's "Tech" stats they are slightly different. 2V-R8 lists tech as one of his stats, whereas Talos does not. From my understanding i was only aware that Aim added to ranged damage. If that is incorrect i will admit to my mistake and happily add Aim to the list of aiding stats!
I may have been slightly wrong and i will admit it. However, the facts about cunning, power and alacrity remain and i advise you not overlook my advice due to a slight error in information.
