@op,

I believe your maths are off.

50db x .10(for skill) =45

45 x .25= 11.25 = 33.75

33.75 x .20 = 6.75= 27


If you are getting scanned then someone is running the focused.

My math shows different numbers

complex damp plus enhance damp plus level five dampening
25+20+10=55%

scan profile minus dampening percentage
50-55%(that's 27.5)=22.5Db

22 or 23 rounded up is below all proto scanners but one which I think is down at 16 Db

@OP

You actually aren't evading the proto. Unfortunately, the stacking penalty is applied to the highest tiered mod.

50 * 0.9 * .8 * (1 - 0.25 * 0.86) = 28.26

Not sure how rounding is handled though.

Base * Skill reduction * ( 1 - Adv Damp * stacking penalty A) * ( 1 - proto damp * stacking penalty B)

where stacking penalty A is 1 (so no penalty)

No. Stacking penalties are applied to the lowest tiered mod on Damage mods.

It seems that when applying stack penalties, CCP orders them from greatest to least and then applies them to the smaller mods. This means mods that give increases have stacking penalties applied to the lowest tier while mods that give reductions have penalties applied to the highest tier

For example,
if you have 2 cmp Damage mods and an enhanced, they would be ordered:
0.12, 0.12, 0.05 (or whatever the actual values are)
Then the penalties are applied from left to right so the first cmp doesn't get a penalty

However, if you are using 2 cmp damps and 1 enhanced damp, they are also ordered from greatest to least:
-0.2, -0.25, -0.25
which means the enhanced doesn't get a penalty

To clear up a few things.

1. if they are using the same fitting code as EVE, which it stands to reason that they are considering many similarities, Stacking penalties are litterally applied in order, mod in slot 1, mod in slot 2, mod in slot 3 ect, which slot is slot 1 is still debated, even in EVE.

2. it's Skill bonus, then Suit bonus, then Mod bonus for how bonuses are applied.

sadly at the moment I am not in a condition to evaluate the maths that have been presented in the thread, pain makes it a bit hard to think properly. I will come back this evening and post the proper maths.

Ratamaq, also left you this on IRC:



Note: This is skipped on my fitting tool, for now.

For the love of God!

Just use the calculator

You may not realize it, but CCP doesn't just throw out a random number when balancing profiles.
I have a feeling there is a reason for it being just at the cusp of detection.

It should require two complex damps on a medium frame to evade a prototype scanner. You have to sacrifice to remain hidden.

All suits have to fit a dampener to evade a prototype scanner, even scouts.
