Slep, your calculations are slightly out...you have to remember each progressive sab you are hitting a target with less weapons than before so it isnt as simple as 8 * percentage destroyed. Here is the basic firmula for anyone interested enough:
(1-P)^8 = W
Where P is the percentage destroyed in each strike, and W is the percentage of weapons remaining afterwards.
If you want to work backwards from the desired inflicted damage then use this formula:
P = 1 - W^0.125
From that to destroy 80% of your enemy's weapons (W = 0.8 ) you get P = 0.0275, or 2.75%. This gives a normal maximum of 2.2% for the rest of us non-replicators. Sounds like reasonable numbers to me, but its not my decision
Edit: Damn emoticon got in there
