so I would like to ask about calculation of damage mainly for drones:
Garde II in Rattlesnake with Galente BS 5/5
Sentry drone Interfacing 5/5
Drone Interfacing 5/5
Advanced Gallente drone spec 5/5
and 3x DDA moduals equipped:

Reported by EFT:692dps

My calculations based on following:
Galente BS 1.1x damage multiplier per level
Sentry drone Interfacing 1.05x damage multiplier per level
Drone Interfacing 1.2x damage multiplier per level
Advanced Gallente drone spec 1.02x damage multiplier per level
Garde II damage multiplier 1.92
Garde II damage base 50
Total drones 5
Rof 4sec
1st DDAII 1.19 2nd DDAII 1.1653 3rd DDAII 1.1083

Damage equation thus is
DPS=50*1.92*1.19*1.1653*1.1083*(1.2^5)*(1.1^5)*(1.05^5)*(1.02^5)*5/4=1041

and I also have 3x fed navy omni links so I get well aimed hits always and on biger targets perfect hits almost always so it extra damage as well.

CAN ANYONE PLEASE EXPLAIN this discrepancy?

Thanks a lot

I do not use EFT myself I got in dispute over damage calculations on Battleclinic I posted my fit saying that it has 900+dps with garde II-s.
and got flamed that according to EFT you can get only 692dps thats why I am asking here. I do not believe that EFT is quantitatively correct in any possible way. its okey during qualitative comparison of fits maybe.

If you see error in my calculations PLEASE point out

Thanks a lot

1.92 x ((0.2 x 5) + 1) = 3.84 drone interfacing
3.84 x ((0.02 x 5) + 1) = 4.224 specialization
4.224 x ((0.05 x 5) + 1) = 5.28 sentry
5.28 x ((0.1 x 5) + 1) = 7.92 ship bonus

7.92 x 1.19 = 9.4248 DDA1
9.4248 x 1.1653 = 10.98271944 DDA2
10.98271944 x 1.1083 = 12.172147955352 DDA3

12.172147955352 x 50 = 608.6073977676 per drone
608.6073977676 x 5 = 3,043.036988838 total
3,043.03698883 / 4 = 760.7592472095 DPS

761 DPS for me

What does the in-game fitting screen tell you?

Also did you leave out sentry dmg rigs or implants?

Edit:

Upon some closer inspection it appears that the Gallente drone specialization is not listed under the Grade II's list of "Affecting skills"

in game fitting tool makes no sense at it says ~800dps from grade II and 900+ from warden II
I have no drone implants on me I did not know those even exist
How can I have higer dps from warden then from garde is beind my anderstanding that is why I ignored the ingame fitting tool
whatever damage multiplier you posted (~12x) as a final result I get if I fit only 1x DDA.

also it seams that I miss understood damage multipliers as I thought that every new level effectivly multiplied the previous result for example if
You have 10 dps and you have 1.1 multiplier per level that actual damage is
10*(1.1^5)=17.7
But you say that it actually works like
10+50% (10% per level) thus 15 is your result.

My current damage multiplier in game says 15.88x

PS: I have no rigs as diminishing return from them is too large (4th modual)

Thank you for your post

What about sentry rigs?

Also the in-game fitting screen is the most correct out of all of them. If you have the Garde's launched then it will read w/e the next highest in the drone bay are which are likely the wardens. Because it bases the DPS from the drones currently in the drone bay is why you are getting reversed results.

Edit: I get 836.83517193045 (837 DPS) from a T1 Sentry rig being added

Edit2: I get 874.873134290925 (875 DPS) from a T2 sentry rig

Edit3: I don't see any drone implants either so I guess there aren't any....was just a shot in the dark :P

Based on the 15.88 number it seems we're missing 30% somewhere.

What is the multiplier with no modules on the ship?

yes exactly that is my concern I plan to go out in belt and shoot 100 volleys from single drone on a roid and average the damage
should be good enough statistics I guess

gallente drone specialisation skill does not effect the damage of sentry drones ^^

I guess it was a glitch now it seems to be fine

damage multiplier is 7.2 without any mods
and I got whatever you posted after applying all 3 DDA II-s hate when this happens
now it looks as it should be

sorry for all the fuss
