Random Question Thread IX: Mathology 101

[Khajit]

Wheres a good spot for light fire win thunder weather that has crabs? Bohayada tree doesnt have any weather up atm and hasnt for me the last few days.
Next a mathology question.
I remember hearing that haste samba when hasso,20%+ haste gearhaste, 2x marches is on is a 30% boost to damage. Does anyone have the math for this or the actual boost a dnc with merited haste samba does give?

I did thunder/wind weather crabs at Vunkerl Inlet [S]. Weather there is frequent, and lots of other people go there too, so easy to team up and burn through the trial quickly.

Basic haste formula is: x/(100-y). x= haste added, y=old haste. So let's see:
10/(100-[20gear+20marches+15haste+10hasso])= 10/35 = .2857, or roughly a 28.6% increase in dmg.

I do have a multi core, but that didn't fix the problem. If I disable the HID items, will it prevent me from using things like my usb controller or headset?

Maybe. All depends on which HID-device is causing the problem. I'd say try disabling 1-by-1 real quick to see which, if any, are actually the problem.

Basic haste formula is: x/(100-y). x= haste added, y=old haste.

Almost. x/(100 - (y + x)).

You can verify that the + x term needs to be there by considering Haste = 99% to 100%. We know that it is an increase of infinity%.

Using x/(100-y), the value you get is 1/(100-99) = 1 = 100%.
Using x/(100 - (y + x)), the value you get is 1/(100 - 100) = undefined.

Oh shit, have I been doing it horribly wrong all this time?
I've been doing (100-old haste)/(100-new haste), so in the case of going from 65 to 75% haste: 35/25 = 1.4 = 40% increase >.>?

I'ma feel really stupid if I've been doing it so wrong for so long <.<

Doh, you're right. Guess that's what happens when I get chatty after being awake 35+ hours.

[Salodin]

Yeah it messes with stuff >_> luckily i didnt disable the mouse and keyboard at same time...

But I did try everything else and it didnt help =( I'm at a loss with what to do...

No, your formula works too.

x/(100 - (y + x))

10/(100 - 75)
= 10/25
= 40%~

Ah few, thanks RR >.>

In case you're bored (cause I am!) I'll show why the equations are equal (basic math really);

Spoilered because it's really not interesting. It's short though.

Spoiler: show

Mine: x/(100 - (y + x))
Yours: (100 - y)/(100 - z)

where x is "added haste", y is "old haste" and z is "new haste".

Note also by this definition that z = x + y.

My answer is output in the form 0.~ and yours is output in the form 1.~: neither are mathematically correct on their own but we can obviously deduce the actual % from them. In order to make the answers consistent, I am going to add 1 to mine.

Mine: x/(100 - (y + x)) + 1
Yours: (100 - y)/(100 - z)

Immediately we can see that y + x = z, therefore:

Mine: x/(100 - z) + 1

Let's eliminate the x. x + y = z, so z - y = x.

Mine: (z - y)/(100 - z) + 1

Converting 1 to a fraction,

Mine: (z - y)/(100 - z) + (100 - z)/(100 - z)

Adding:

Mine: (z - y + 100 - z)/(100 - z)
Mine: (-y + 100)/(100 - z)

Mine: (100 - y)/(100 - z)
Yours: (100 - y)/(100 - z)

Hurrah :D

[Fryte]

I am looking to start OAT Scythe and am rather clueless about the VNMs. What tier1/2 VNMs can I solo and eventually get a Verthandi pop? Jobs available to me are BLM, SMN, DRK, PLD, COR, THF, and RDM.

[rog]

Any t1 is soloable, and i don't think either one for verthandi can be soloed.

Hurrah :D

I got confused because of his equation befor you made the small correction, which gave him the 28ish% boost, not the 40% I got >.>

Kaeko solo'd Urd on rdm/drk

All 10 T2 are soloable with pin cheese. For Skuld, you just need a MDT set and then run from chainspell since it's glitchy and will sit there if you're out of range. For Urd you just pin it, keep it 15'+ away and lock it in trance mode so it doesn't cure itself. /DRK stun is just backup. Both fights take considerably longer than the other 8 though since you can't nuke effectively. I wouldn't recommend solo farming those 2 unless you have a lot of patience (or luck).

[Yugl]

Is anyone compiling the list of NMs/Pin areas for VNMs? I might try to solo them when I get the spare time.

I have like 4-5 NM posts i still have to make but finding time is hard for me atm

[Neosutra]

Can anyone give a good estimate on how much the new 20 def ring(s) would reduce your damage? It peaked my interest and I am trying to determine how they compare to Jelly/Defending ring.

I know it will fluctuate based on enemy attack, but assuming the enemy isnt vastly over cap on attack, what would be the net PDT difference?

[Neosutra]

From what I see:

Damage = Base damage X Pdif.

If we let Base damage remain constant for this test and examine various levels of MOB attack, we get:

400 player def, 400 enemy attack = pDif of 1. So a 100 base damage hit would hit for 100 damage.

Add the 20 def ring:

420 Player def, 400 enemy attack = pDif of .952. So a 100 base damage hit would hit for 95 damage.

So at Player def = Mob Attack, the new Def+20 ring adds 5% PDT.

Let's examine at different Pdif ratios:

400 player def, 800 enemy attack = pDif of 2. So 100 base damage hit would hit for 200 damage.

Add the 20 def ring:

420 player def, 800 enemy attack = pDif of 1.904. So a 100 base damage hit would hit for 190. Again, a 5% PDT reduction.

Let's go to the other spectrum:

400 player def, 200 emeny attack = pDif of .5. So a 100 base damage hit would hit for 50 damage.

Add the 20 def ring:

420 player def, 200 enemy attack = pDif of .476. So a 100 base damage hit would hit for 47 damage (not sure if damage is rounded up, so maybe 48?). That again is 5% PDT.

Now let's vary the player defense:

600 player def, 600 enemy attack = pDif of 1. So 100 base damage hit would hit for 100.

Add the 20 def ring:

620 player def, 600 enemy attack = pDif of .967. So a 100 base damage hit would hit for 96~97 damage (3-4% PDT).

Or examining extremely low defense:

200 player defense, 200 enemy attack, pDif of 1., 100 damage per hit.

w/ ring: 220 player defense, 200 enemy attack, pDif = .909. 100 base damage hit would hit for 90~91, a 10% PDT difference.

So it seems that the controlling factor here isnt the mob attack portion of pDif, but rather the player defense before the ring is added. The lower your defense before


If excel worked on this computer I'd do a chart. But it seems in conclusion:

If you're at 400 def or less, one of these rings will provide more PDT than jelly ring, without the magic damage +.

If you're at 200 def or less, one of these rings is a defending ring..

If you're move above 400 defense, these rings start to trail off on PDT on a linear scale.
