$\bigg(1+\mbox{posaug1}*\left(1+.04*\mbox{AT}\right)+\mbox{posaug2}*\left(1+.04*\mbox{AT}\right)\bigg)*\cfrac{1}{1 + \left( \cfrac{1}{1 +\mbox{negaug1} } -1 \right)*\left(1+.04*\mbox{AT}\right)+ \left( \cfrac{1}{1 +\mbox{negaug2} } -1 \right)*\left(1+.04*\mbox{AT}\right)}$

if the aug says +40% then posaug1 is .4
if the aug says -40% then negaug1 is -.4

Ok I'll explain it the best I can.

Let us say we have our stats start out at 0. Now if you have a +100% (x2) bonus, you will get +1. If you have a +200% (x3) bonus it is +2.

The direct opposite of a +100% bonus would be a -50%, which is -1. Therefore it stands to reason that the direct opposite of a +200% bonus would be -2, which works out to -66% when you invert it back (which if you multiply out by x3 evens out exactly).

Here is the code we get when initially applying the bonuses to find a number relative to zero. The bonus is a number relative to 1, so for example -50% would be 0.5, +30% would be 1.3, etc.

 if (bonus > 1.0)
   factor += bonus - 1.0;
 else
   factor += (-1 / bonus) + 1;

Here is the formula for reverting back to a number relative to 1 so that it can be easily multiplied out by the rest of your ship stats.

   if (factor < 0.0)
     factor = (-1 / (factor - 1));
   else
     factor += 1.0;
