    seen 52 times at auction total
    averages for this item:
    buyout: 82.50 <---------------- A
    buyout median: 74.38s <------B
    last 32, median: 74.38s <-----C
    scanned 3, median: 1.45g <---D

    first let me make sure i have this right. A is the average buyout for 52 auctions. B is the buyout median for 52 auctions (historical median). C is the buyout median for the last 32. D is the buyout median for the last 3 (last scan).

    here is where i'm confused though. how can B and C be the same price if one is based on 52 auctions and one is based on 32 auctions? and i checked with many other items, and B and C match on all of them.

    btw, the numbers above are taken directly from a tooltip for a warp burger

    Median of {5, 6, 7} is 6 (center value).
    Median of {4, 5, 6, 7, 8} is also 6.

    If the median value has quite a few examples of it, eg {5, 6, 6, 6, 6, 6, 7}, even a lot of auctions on one side or the other might not change the median. {5, 6, 6, 6, 6, 6, 7, 8, 9, 122, 345} still has a median of 6.

    ya, i know how median works, but i'm confused at how B and C matched on all the tooltips i've checked. you would think that they would almost never match when you are looking at something with hundreds of auctions seen vs the cap of 35 for the last x stat. i will keep looking at tooltips though, as surely i couldn't be the first person to notice this if it indeed was a mistake in programming.

    i checked about 15 more tooltips of various items, and every single one is exactly the same; the historical median (B) matches the last 35 median (C). i'm sure that this is no coincidence now. so i'd like to know if this is an error or not. i mean i can check 100 more items if you want, but i have already looked at around 50 different items, and they all match. i'm pretty sure either the historical median (B) is wrong or the last 35 median (C) is wrong. and by wrong i mean that they are either both the historical median or both the last 35 median.

    if they are both the last 35 median, then that means there is no historical median in the tooltip, and that perhaps even the average buyout (A) is not even historical, and that everything is just based on the last 35. quite an accusation i know, but i can't see it any other way. any of you can try it for yourself if you want. go try and find a tooltip where the historical median differs from the last 35 median. and remember that the historical median is listed in total buyout, so you must either 1. divide by stack number or 2. remove one from the stack and analyze that.

    SilentBob420BMFJ,

    Another of the big enhancements in Advanced is the choice to use multiple statistics, even ones of your own devising, or to use a single statistic that you feel is the most accurate. There were changes made within the past few months to help make the AuctioneerAdvanced statistics even more accurate, and have seen some promising results thus far.

    At this point, with the upcoming release of 3.02 and the WotLK, we more than have our hands full with one suite of tools. Even though that is surely unsettling, we will not be going back to address the statistics engine in AuctioneerClassic or to determine the cause of the issue, if it is something locally on your installation. Either determine which value(s) you would like to use or use the WoWecon value, as you have noted in the past.

    Happy Sales,

    Nikk :shades:

    i found one that was different. although it was only different by a very small amount (something like 3.52g vs 3.40g), it was still different. so this either means there is some sort of weird error in programming, or that there was some huge coincidence that all 50+ tooltips i checked happened to be the same, combined with the way medians work, and how the median could often be somebody putting up a large number of them, thus changes on either side of the median wouldn't affect the median.

    i still say that something isn't right, and that when you have an item with 100+ auctions seen, i would think the last 35 would be different most of the time. of course, i haven't scanned too much, so most of the tooltips i checked had less than 100 items, but still, i checked many with 100+. AA has the same stats as i listed above, it just has some extra ones too, so i would think that it would be the same case on there. i dunno, i guess this means that you can pretty much treat the historical median the same as the last 35 median, since they are the same 99% of the time.

    i know you aren't working on AC anymore, but if this indeed was some sort of error, does that mean that it has been like that for years? if it was/is an error, i'm curious which one i the correct one (and which one is just copying the other or something); the last 35 or the historical.

    i wouldn't even expect you guys to take this super seriously and dive into the code even if it was AA, so don't think that i'm saying "you need to fix this, i want it fixed immediately, cater to what i want" or anything like that. i just ask questions and hope to get an answer that explains how i misunderstood something, how to do something, why something isn't working, etc. i'm going to wait as long as possible to get AA, in hopes that you guys make it more to my liking. i don't think it's that far fetched to think you will completely change something (such as compact ui and it's features) or something like that within the next few months, is it?

    so are you guys completely reading for wotlk then with AA?

    at the moment we are focused on getting a release version of AA out if we can - not sure if this will happen. next is a version that works with 3.0. after that is a version that works with wotlk.

    what is this 3.0 version? i'm guessing it's a patch that makes sure all BC players are able to play with all WOTLK players pretty much?

    Right. It's the equivalent of what 2.0 was for BC. (note that 2.0 came out a little bit before BC)
