Indeed that is a typo, lol. It even showed when I used that very equation to figure out the bonuses he'd get.

No it fucking isn't. Go back to my instructions in this thread and work out why. There are too many possible places for you to be making your error for me to set you straight directly. Or you can post your complete reasoning and I'll show you where you are wrong. Every successive post you make that doesn't do one of those things just emphasizes your error.

Okay, my bad. It isn't a typo. You just forgot a second set of parenthesis.

The only forgetting going on here is your calculator forgetting order of operations.

Ahaha well you can blame Microsoft's crappy calculators then!

Now, where is my TI-84 plus? That wouldn't have lead me to believe you, a math professor, messed up your math!

'sup baby

so to clarrify, does stacking augs reduce their effectiveness or do they stack 100%? e.g. 50% +50% = 100%/etc

Because ive ran over the instructions over and over and i just cant grasp the concept here but ir eally want to...

+50% + 50% = +100%

Positive bonuses ALWAYS add up.

Negative bonuses add up in the form of n/(1+n).

e.g. if you had -60% visibility aug and you used 3 of them, the bonus would be like this:

(-0.6)/(1 + (-0.6)) + (-0.6)/(1 + (-0.6)) + (-0.6)/(1 + (-0.6))
or
-1.5 + -1.5 + -1.5 = -4.5 = B.

now to convert again, simply do B/(1 - B)
or
-4.5/(1 + 4.5) = -81.82%

The lowest visibility you could have is -97.24% which is 4 Sup. Stealth augs on an Engi Vulture with Engi class 20, AT25, and IT5.

Wait, so 5 Sup. Stealth augs on a Battle Sphere has less vis reduction than the 4 Sup. Steath augs (regardless of end result vis)?

And Engineer level 21 doesn't do anything?

I was more basing it on the end result, but yes, your case would provide more -vis from augs and skills than the actual vis.

4x minor docking still the best setup.
