Your example is dealing with vehicles, which use condition tracks. Mine is dealing with barriers, which use the barrier rules.
You're right, except that its very hard to do that. Structural material, such as brick/plascrete, which I would assume most buildings outer walls are made of, has a structure rating of 11. Thats for breaking through it. Doing 10 damage to the wall doesn't blow a chunk out of it. And it doesn't matter if you consistently do 10 damage to it. Until you hit 11, you don't break a hole in it, and it doesn't have a condition track, so previous damage doesn't carry over.
So I could waylay against a concrete wall with a sledge hammer, and if I don't beat it's structure; it remains the "Rock of Gibraltar". Is there no erosion in the Shadowrun universe?
I cannot agree with the rules here. I will argue that each square meter has damage boxes equal to it's structure rating, and if it experiences damage overflow; it will overflow to an adjacent meter.
A "Powerball" may not demolish a structure in a single application, but I will suggest that the area within the powerball's radius does create an environment of "Terminal Erosion". Two or Three powerballs will have a cumulative effect.
I am not singling you out Tarantula, you just had the explanation neatly packaged. I can see where the RAW suggest no follow up on a second attempt to attack the barrier (although the example does), but I refuse to believe that any action has no effect. To align my opinion to the rules, I will say that the gamemaster must re-evaluate the material in question for every blow. Reinforced Material (8/9) de-stressed by a handful of SMG rounds may no longer constitute Reinforced Material. The bullet riddled security door may now only rank Heavy Material (6/7) or less. Of course, the Gamemaster must decide.
