I understand the stacking penalty is applied to Tracking disruption drones

I was trying to work through the maths first with an acolyte TD-300

0.95 effect - that is 5% reduction

if i use three TD-300's there is an 87% penalty limit for the second one (4.25% reduction) and 57% percent penalty for the third (2.85%)

So altogether that is 5+4.25+2.85 =12.1% reduction (x 0.779)

Have I got the math right on that?

If so I was wondering instead of using 3 light TD-300's that take up 15m3 cargo space would it not be better to use one Infiltrator TD-600 and one TD-300 which also take up 15m3 space

The TD-600 gives a (x 0.88) 12% reduction added to the second TD-300 4.25% reduction = 16.25% reduction

(Only works if the TD-300 is counted second in the stack though)

This seems to need no extra drone space, improves the tracking disruption and allows for another drone to be operated

The first question is have i got the calculations right?

and second is how do 'different' drones with the same stacked attribute combine their attributes (largest counted as first, random, smallest counted as first)?

The maths on TD, TP, SD, SW and EV drones are exactly the same as they are on the equivalent modules.

ie :

1st mod: c(1) = 100.000% effectiveness
2nd mod: c(2) = 86.9119842% effectiveness
3d mod: c(3) = 57.1037996% effectiveness
4th mod: c(4) = 28.2469117% effectiveness

For "mod" (module) substitute drone and you're there. Also nothing in Eve is additive even when the description suggests it is.

Edit - all of these drones are mainly useless, certain situations excepted (ie its a tarp or bait to hold you up)

Edit2 - if you wonder why they are useless then look at their optimal and max speed. With the exception of the SW drone (highly situational) the rest are a waste of dronebay space.

Edit3 - if the same attribute is being modified then you will get stacking penalties regardless of what module/drone modifies the attribute.

Thx for your reply Othran

I suppose the main question I am asking is - is their a preference to which drone stacks first.

Is it the larger TD-600 or the smaller TD-300?

If it is the TD-600 first and the TD-300 is at 87% then the bonus is 16.25% reduction

If the TD-300 is first and the TD-600 is at 87% then the reduction is a smaller 15.44%

Not a huge difference but was wondering if anyone new the mechanic?

Largest bonus first then the second largest and so on.

So the drone with the biggest bonus gets the full 100% and so fourth. Same with modules.

Thanks Linda

Will help when i make other calculations

The problem with these drones, is that there is almost never a situation where damage or ECM drones aren't the better choice. ECM drones are pretty awesome, and make soloing in a battlecruiser hull a lot more viable.

In a carrier, you might be able to neut a hictor's bubble off with EV-900s quicker than you can chew through the colossal tank with damage drones (and EC- drones won't stop him from bubbling). The WDFG is pretty cap intensive to run.

e: also pretty sure EV drones don't get stacking penalty'd.

Hang on, if you launch 2 or 3 ecm drones at a target then there is a penalty for that ? So are you supposed to just launch 1 drone instead then ?

For my part I know nothing with any certainty, but the sight of the stars makes me dream.

The ECM effect doesn't stack: you are either jammed or you are not. Increasing ECM drones is good, as ECM is chance based, and it increases your likelihood to jam.

Chance for at least one successful jam = 1 - (1 - jam_strength / sensor_strength ) ^ number_of_jammers
