I like atmas drop calc better, though, check signature :)

[HiTS]

Atma's drop calculator has a few bugs in it, but if you it qualitatively it's fine.

[Taurean]

Why is atma`s better? I thought it only worked for SP?

Care to name them?


@ Taurean: It works for everything.

[Taurean]

Alright, i might check it out then.

[HiTS]

No, because I'm not a code demon. All I know is that it has something to do with an error in the way partied and non partied bonuses are applied to the /pX when calculating the drop percentages. The errors are minor and only appear to be something the order a few tenths of a percent either way. That's why I said that, as good qualitative guide, it's great, but if you want to work something out down the the twelfth decimal point it's probably not good enough. It also lists a NM uber Diablo, with a mlvl 110, so if you are not paying attention you can confuse it with the "normal" NM Diablo, mlvl 62.

ATMA reads 100% correctly from the game files. The oddities are due to Blizz writing uber diablo in the game files one way and then circumventing most of that in the server side game code. Basically, ignore the mlvl 110 diablo and everything else is fine.

Unpartied players vs. partied players has been handled for several years in ATMA, of course you have to understand what that means to make proper use of it, but there's no getting around that.

And yes, the odds are the same for ladder as they are for single player so it works for ladder too. (A number of items that can't drop in non-ladder mess up the odds a little bit for non-ladder)

Anyone looking at multiple decimal points is ignorant as to how probabilities work and should stay away from calcs altogether.

What do you mean by that? Why would anyone use calcs then, if it is how you say?

Of course i run enemies with 0,0050% chance of dropping that specific item i want if it does, provided there are numerous enemies of both to be killed, either way i don`t expect it to drop in the near future.

[dainbramage]

He's making the point that in reality there's no practical difference between a 0.0005% chance to drop something and a 0.000500001% chance. They're both pretty damn close to 1/200000. It's also not like you need some precise number and have to exactly hit that number somehow... all you're doing is killing things.


@HiTS: What jjscud said... hence why I challenged you to name a bug.

[Taurean]

Well .. i agree to a point.

[HiTS]

That, in itself, IS the bug. In the scheme of things the difference is so small that for the average player as to be non-existent. On the other hand, if you are the type of person that counts their runs in the tens of thousands, and there are a number of nutjobs that do, these errors tend to add up. That is why I used the term qualitative not quantitative. I may be splitting hairs, but it IS worth mentioning, especially for the nutjobs out there.

You could use the same argument and say that every single drop calc is bugged. They don't take into account rounding error in the game code or things like items dropping on invalid spaces.

I'm not saying they aren't more accurate than ATMA, I'm just saying that the extra info/precision they provide will never help anyone in any way. Even for someone like me who does count several different runs in the tens of thousands.

I suspect that things like items dropping on invalid squares and out in space or lava are much more significant than more than a handful of decimal places so any drop calc that does list it out to 12 decimal places is inaccurate anyways.

[HiTS]

I agree with you, but I believe that it is both a bug and that it is worth mentioning. Too many people get carried away with a drop calculator and say "but ATMA said ......" without any concept of what the probability actually means. That's why I'm banging on about qualitative over quantitative. Monster A has better chance to drop Item Z than Monster B does is more important than Monster C has a probability of dropping Item Y of 1.076 E-7. When you add into the equation factors like the fact that you may be able to get three /p3 Meph runs in the same time as you can do 1 /p1 Baal run, the fact that Baal has a relative 10% greater chance of dropping a specific item becomes almost irrelevant. Don't get me wrong I use ATMA all the time, but if is important to let people know that it isn't the be all and end all and that is just another utility, a guide if you like, to aid you in the game.

Absolutely, sounds like were getting to the same point from different directions.

[Taurean]

ATMA doesn't work with Vista.

I Hate Vista with a burning passion right now.

[Taurean]

We've made it clear, you won't listen, game over.

[HiTS]

You do realise that ATMA is superseded?

[Taurean]

o_O With what?

[HiTS]

With the program written by the guy you just banned.

[Taurean]

Doh...

For real? That's bad man ^^ Should i un-ban him? Although i dislike any form of advertisement, if it's helpful to other people it should be ok..

[Omnicide]

Yeah I only gave him a warning because his intro posts was all about that program. I didn't ban him because it's still pretty much ATMA.
