Hi, apologies for the n00b question:
Are skills compound? e.g. when I train a skill that decreases cpu load, does each rank in the skill take X% off the original cpu load? Or, does each rank take X% off the cpu load including previous skill deductions?
new load = original - ( rank * X ) %
or
new load = ( original - ( rank * X ) % ) - ( rank * X ) %
Thanks

Each skill level is additive of itself, so your first equation is essentially correct, although the math would be:
new result = original result * (1-(skill * level))
as it's a reduction to fitting costs.
Different skills and module effects are multiplicative though, so suppose you had a hardwiring that reduces CPU costs, you'd get:
new load = original * (1-(skill * level)) * (1- hardwiring)
This applies to every skill/module/implant interaction in the game, with the sole exception of the special connections skills, which add instead.

Basically, seperate skill levels in the same skill are additive, everything else is multiplacative (is that a word?).
So the Electronics skill at lvl 5 increases your CPU by 25%. Adding a 10% Co-processor makes the total increase not 35%, but 1,25*1,10=1,375 or a 37,5% increase.

So, for example... suppose I have:
Combat Drone Op IV Drone Interfacing IV Gallente Drone Spec III
Then for a Gallente medium drone, I would get:
base * (1.2) * (1.8) * (1.06) = 2.29x base drone damage
whereas if skils were additive I would have only had 2.06x base drone damage.
Is this correct? Someone who knows, please confirm this is how it works.
Interesting to note that if I were to pick one skill to train next from here:
Combat Drone Op IV -> V... increases total drone damage 4.2% (not the full "5%") Drone Interfacing IV -> V... increases total drone damage 11.1% (not the full "20%") Gallente Drone Spec III -> IV... increases total drone damage 1.9% (not the full "2%")
Just something to keep in mind when you're calculating your bang-for-buck in terms of training skills... once you get past level I in a skill, your "marginal" percentage benefit decreases (especially at level V). Of course, the "amount" of damage increase is of course the same at level V as it is at level I... but I know I tend to look at those percentage numbers in the skill descriptions and have to remind myself they don't tell the whole story!

This is correct. Bear in mind you've rounded your result - EVE will use the calculated value even though it'll display the rounded.

Let me see... 2.2896 base Combat Drone Op 5 = 2.385 of base Drone Interfacing 5 = 2.544 of base Gallente Drone spec 4 = 2.3328 of base
In terms of relative damage increase, your values are correct. In terms of absolute damage (compared to base) you get the the listed value increase.

There is no such thing as infinite precision in computer science. The EVE code will indeed round the result, but it may carry more decimal places than the example ;P

double is going to have more precision than you care about.
Oh, on the precision note: everything in eve appears to be a double, even the stuff that doesn't show a decimal part. --- Our greatest glory is not in never failing, but in rising up every time we fail. - Emerson |

LOL, I could give a flying #$%ISK if it's 2.29 or 2.2896... I specifically truncated because people are always using excessive precision on these boards, and frankly it often muddles the issue at hand.
If I ever find myself in a situation thinking "Dang, if only my drones had each done four hundredths of a percent more damage per hit I would have won that battle" then I will come back here and apologize for trying to keep things simple.

Oh? You'd like your attributes truncated and the integer values used to calculate your SP/minute would you? 
People tend to use 'excessive' precision because that's what the game uses and with the scale of the bonuses in this game, that little bit extra makes all the difference.
For example - 0.04% damage difference. Over a hundred hits, that's a 4% damage difference. If I haven't done my math wrong, 100 hits would take 5 drones about 60 seconds, assuming 3 seconds/shot. With base damage for medium drones, that's an extra 50 damage over a hundred hits, all for the sake of 0.04% difference. 
While this wouldn't make much difference in PVE, in PVP it can mean you waking up in a medical pod in station or you scooping up a whole ton of loot from the other ship.
I think a large percentage of the player base comes from a technical or scientific background, so this level of precision comes naturally. I personally don't think it muddles the issue at all, but I guess other people's perceptions may vary.
