Also, ErikB didn't say no repulsors for lift, he said no hovering. The difference is in cooling. If you're hovering, there's no airflow to cool the hovering mechanism, so there's a time limit. If you're flying, you can use the repulsors for lift and the ion engines for thrust, which causes airflow, which cools the repulsors mechanism. However, landspeeders can clearly hover indefinitely.
That makes total sense and rationalizes the PoV. Thank You, Lunatic Pathos, for a brief and well-thought out response to something that wasn't even your original post. I wish most post here were so intelligent.
Back to the OP, I wouldn't mind an answer to #4, if 2 Advantages are used to trigger the additional hit that had 3 successes, is the total:
8 + 3 + 8 = 19
8 + 3 + 8 + 3: 22
THe second part of your answer is more correct, but doesn't account for soak. The concept of a "hit" is key here, since attacks with weapons with the linked or autofire qualities and two-weapon attacks may score multiple hits from a single attack. A single hit represents a single projectile or bolt striking a target. Soak is substract from each hit separately (final week beta notes, pg 7, Performing a Combat Check, Step 6: Reduce Damage, Check Wound Threshold, and Apply Critical Injuries (pg 133).
How uncancelled successes are added to damage in the case of multiple hits per attack also differ based on how the extra hits were generated. For the Linked and Autofire qualities (relevant to this example), damage equal to the number of uncanceled successes is added to each hit generated by the attack. (final week beta notes, pg 6, Autofire (pg 133), and original listing for Linked quality (p106)). For Two Weapon Combat, Each uncancelled success form the attack roll deals +1 damage to the attack, distributed as the attacker sees fit (final week beta notes, pg 8, Two Weapon Combat).
SO, in the original example from the OP, if linked were triggered, the attack would deal 2 hits, worth 11 points of damage each, and each subject to reduction by the target's soak.
I don't like saying "22 damage" because that could be misconstrued as only being subject to soak once, instead of once per hit.
