-Warning-
Not the most clear/well written post xD

So I was wondering how to calculate Attack speed when considering both speed buffs and debuffs at the same time.

Came up w/
Interval + (Interval x Debuff) - (interval x buff) = New interval, round down to the nearest .05 interval and then convert to APS w/ Elena's handy chart
http://pwi-forum.perfectworld.com/showthread.php?t=279561&highlight=attack+speed+basics

I tested for all values from .55 to .80 w/ 25% buff from demon spark and 100% debuff from CoD and it worked fine.

But then there is this

Assuming @ .15 interval 100% debuff 25% buff I get .2625 for attack duration which rounds to .25 and converts to 4.0 APS not 5 ^_^;;
so I think I'm wrong somewhere, or the dude has super -.15 IBH fists / high str relentless courage genie used after demon spark (if relentless overrides demonspark).

blah blah blah so long... what I was actually wondering about is if a fist wearing sin w/ only -.5 interval (so .2 instead of .15) and DEMON CoD (predicted as 70% debuff instead of 100%, just assume is true for now) would still be able to reach 5.0. Was trying to do the numbers myself but it wasn't working so posting here.

Before anyone says [though some1 already said this] that the dude has .15 interval which doubles to .3 from CoD and then w/ demon spark and rounding goes to .2 which = 5.0 aps. My .55 interval doubled from CoD goes to 1.10 and w/ demon spark ends up at .95 or 1.05 APS. Whereas my archer w/ 1.10, demon sparks and ends up at .8 or 1.25 APS, so definitely different due to ah... "double counting" (ok that probably didn't make sense but the point is no you can't just double .15 and then apply demon spark normally which takes .3 interval to .2 interval or 5APS under NON-debuffed situations)

Edit: should be moved to assassin forum, had too many windows open posted wrong place.

    Considering Chill of the Deep isn't a regular debuff (can't be purified etc) means it might be an exception or work differently. If the screenshot isn't editted then the answer would simply be... they stack. .15*2*.75 = .225, rounded down to .2 = 5/sec.
    Wondering how much longer these **** packs are going to be around.

    No it shouldn't, my .55*2*.75=.825 which should round to .8 interval but as i already said it goes to .95 or 1.05 APS which you do get from .55 + (.55x1) - (.55x.25) = .9625, and yet somehow it does -.-

    0.15 + (0.15 * 1) - (0.15 * 0.75) = 0.1875, which would round to 0.20 sec/attack

    I'm not sure how you got the number 0.2625 .

    I used -(.15*.25) instead of - (.15*.75) uhm tbh I don't really know what I'm doing w/ these numbers. But the - is on the outside so I think whatever is in this part - (interval*buff) should become bigger with larger increase to attack speed. I am guessing that .75 came from 1-.25 if this is true then a 50% increase to attack speed would be less of a buff then 25%. maybe I am supposed to use 1.25 instead of .25 o.o

    Ok i think i don't get it ._. when I try to use the formula goes like this

    w/ all interval gear, 100% debuff and 25% buff .15 + (.15 x 1) - (.15 x (1-.25)) = .1875

    same but 50% buff .15 + (.15 x1) - (.15 x (1-.5)) = .225

    in this case both round to .2 so its the same but its seems like a greater increase to attack speed results in less, if I am understanding this correctly ?_?

    What I am really wondering is if .2 interval is sufficient to hit 5.0 w/ Demon CoD [predicted as 70% debuff to speed instead of 100%] So i tried to make a formula, and it worked for .55 to .8 interval but didn't work for .15 >_> I really hope that I am just misunderstanding the above formula cause

    .2 + (.2 x.7) - (.2 x ( 1-.25)) = .19 --> 5 APS n_n

    Your numbers are correct.

    25% Speed Increase => 0.1875 attack DURATION.
    50% Speed increase => 0.2250 attack DURATION.

    The lower the attack duration, the higher the attack speed.

    So since 25% speed increase has .1875 duration, lower than .2250, it has faster attack speed than 50%? That doesn't make sense...

    I think we have two issues here. First is the concept:

    If your attack duration is 1 second, you attack once every second.

    If your attack duration is 0.5 seconds, you attack twice every second.

    Your duration is how long you wait until your next attack.

    Does this part make sense to you?

    The problem is that you are using wait - (1 - wait * change%). This is equivalent to wait + (wait+change%) - 1 or, in other words, a faster attack speed increase makes you wait longer.

    (Elenacostel, I think your equation needs a minor tweak.)
