Hrmm, so just for an example, the calculations of a 6 Hephaestus (50% capacity) Auged Thatch & AT 25 & Support Focus 20 (180% capacity) would be:

1) 55,000 * (1 + (0.5 + 0.5 + 0.5 + 0.5 + 0.5 + 0.5) * 2) * 2.8 = 1,078,000

or

2) 55,000 * (1 + (0.5 + 0.5 + 0.5 + 0.5 + 0.5 + 0.5)* 2 + 1.80) = 484,000

and I'm guessing definitely not:

3) 55,000 * (0.5 * 2 + 1)^6 * 2.8 = 9,856,000

i.e. does the class bonuses get simply multiplied on top? and what about aura/overloaders/item bonus'/tertiary skills/bar skills and such? are they simply an added bonus? or a separate multiplier?

Just asking since I was gonna make some storage thatches

Number 1 is correct. As I explain in my original post, overloaders and item bonuses add in like augmenters without AT. Everything else (modifications, class skills, bar skills, etc.) multiplies, with a few important exceptions (e.g. Multifiring, SD RoF). Number 3 used to be the correct calculation before the big rebalance some years ago.

how about a excel spreadsheet with this stuff in it XD

If +25% and -25% shields cancelled then -25% shields would not correspond to removing a quarter of your shields, but rather removing only 20%. That's no more complicated than the fact that 75% of 125% is not 1.

It really calculates everything this way? Why is it so complicated?

It should be simple. +25% and -25% should cancel each other out because they're adjusting base damage, not each other. If you have a weapon that does 100 damage, and two augs that add +25% and -25% damage respectively, it should calculate the bonus damage each one gives, add them together, and apply the result. It's the most intuitive way. One aug wants to add 25 damage, the other subtract 25 damage, and the result is +0 damage, or 100 damage total. If it were +25% and -20%, it would be +5 damage, or 105 damage total.

Isn't that really a better way of calculating it? The current system seems flawed.

Very good point, but disallowing absolute zero values by complicating the calculations makes everything counterintuitive.

It would be better if the absolute minimum value anything can be is 1 (visibility an exception which should be able to go lower than 1), so that two negative bonuses of -50% and -50% would be 1, not 0.

If you used two tinted augmenters, that's -140% visibility and -100% radar. Total radar would be 1, and visibility would depend on whatever the lowest value is determined to be, maybe .1 (or whatever). Stealth augs would work the same, two of them would drop you to whatever the lowest value possible for visibility would be.

I'm admittedly not good at math, and that augmenter calculation wiki page is greek to me. In the current system, what are results of using two tinted augmenters? If -140% visibility does not take you to the absolute minimum visibility allowed ingame, then maybe those augmenters shouldn't be saying they reduce visibility -70% each.

4. n_1 = -20%, n_2 = -20%, T = 1
B = T x ( n_1 / (1 + n_1) + n_2 / (1 + n_2) ) = 1 x (-0.25 + -0.25) = -0.5
B / (1 - B) = -0.5 / (1 + 0.5) = -0.33 = -33%
Multiple negative bonuses are not directly added together.

So you're saying -70% visibility and -70% visibility = -82.4% visibility?

I cannot give you any constructive criticism other than maybe adding some more examples with various aug values (yeah I see that example and my eyes glass over), but I would suggest that the displayed negative values ingame be changed because apparently no negative aug actually does what it says it does especially with multiple negative augs.

2. n_1 = -20%, T = 1
B = T x n_1 / (1 + n_1) = 1 x -0.2 / (1 - 0.2) = -0.25
B / (1 - B) = -0.2 = -20%
A single negative bonus with T = 1 goes unchanged.

I'm going to post a suggestion for a "preview" mode for augmenters and somewhere to see the actual values of all your augs, perhaps under the Ships tab.
