...Cyberlegs don't change your base movement speed at all
It feel strange that your base movement is not calculated from the
average agility of all limbs involved. Have this been clarified...?
It is clear that when you use
a particular limb for a
test you use the rating of that limb, but in
all other cases (when you for example is
not taking a
test) you use the average value of all limbs involved in the
task (they don't use the key word
test here which might or might not be intended).
If
all other cases include movement or not depend on if movement can be considered a
task or not.
Sprinting is a skill test so at least this qualify as a
task no matter how you read it.
- When you take a sprint test you use the average strength value of all limbs involved in the task.
As for the max aug of +4... I think they were asking about +4 to the limb (i.e. Enhancement 3 plus Redliner +2 for four limbs would be 5 and if that would be legal or if it would max at +4).
Cyberlimbs are intended to have attribute values of their own, independent from your natural rating. Without house rules in place you can customize cyberlimbs up all the way up to your metatype maximum value no matter what your current natural rating is. If your natural rating is low then your cyberlimbs can be customized to break the aug +4 limit even
before you add enhancements.
Since it is not spelled out otherwise, I would use the average of arm/arm/leg/leg/torso for Physical Limit.
It have been clarified that cyberlimbs does not alter your Physical Limit (in any direction).
