Instead of rolling dozens of dice, just roll one pair of percentage dice for every attack.
Declare the target and the number of attacking factors and if you roll the number before the slash or less you damage the target and if you roll the number after the slash you destroy it.
For example if three fighters with a total torpedo factor of 6 attack an undamaged Terran CL (1+3) at long range then they have a 49 percent chance of at least flipping it to it's damaged side and a 4 percent chance of destroying it in a single attack.
