The Technical Aptitude talent has the unique honor of being the only time-reduction talent that actually stacks, reduces by 25% rather than 50%, and lacks a secondary benefit which normally is the aspect that stacks with multiple ranks. Where this becomes a problem is when all specializations of the game are available. The Slicer from the Edge CRB tree has two ranks of the talent which would take 100 XP to get both, Desperate Allies's Analyst has one as a 5 XP talent, and the Artisan from Endless Vigil has a 5 XP talent as well. If we start from Artisan, that means 160 XP will get four ranks which by the normal stacking rules for time would result in the duration reduced to 0, or basically an action.
Is there something I'm missing, or is a dedicated speed-programmer really able to do things like programming Elimination protocols per Special Modifications in a few seconds? If I am right, then that is truly awesome! I suppose dedicating a build to more rapidly performing Computer checks has earned its ability, and I might look to this as a potential build in a future game!
