    Well, not necessarily. For example, go check out Top 100 Grossing in Utilities.

    Fake-a-call and Night Stand are two apps that jumped 80+ from the recent glitch. They are currently ranked #3 and #4 Top 100 Paid in Utilities, but are ranked #35 and #37 Top 100 Grossing in Utilities.

    With a proper ranking algorithm in place, these apps would not be #3 and #4, but moreso #29 and #30. Sure, it's a lot higher than they were before the glitch, but it is not making them 1000 sales a day or anything.

    True but also some apps won't recover from the heavy drops they have suffered. And I'm not so sure this was an unintentional glitch. After all someone had to have at least changed something at some point. And I doubt apple forgot to test it first.

    I can confirm this.

    Again, see post #2.

    Great enthusiasm though, CommanderData :p

    I deem this the App-pocalypse

    TanZen is sitting halfway between the old rank and the pseudo rank. My competitor is now ten behind me. This does not reflect positions before the incident at all, but does suggest that the last two day's sales have been applied in some way. Otherwise, I'd be down another 20, and they'd be down another 50+.

    Maybe they fixed it now and this is the fall out.

    Exactly.

    The ones that experienced sales increase from the glitch have received an expected boost.

    Point is, there is no new ranking algorithm, and currently it's back to calculating the ranks how it used to (7day weighted average)

    App Store getting flooded

    I think its more than that if Apple wants to really mature and not also be turned into a 'trash store'. They absolutely must also start policing what or how apps get approved. I've noticed it's actually getting worse EACH DAY in that each category is starting to flood with many duplicate apps by the same developers, with just slight modifications to sprites or color. As well as the proliferation of apps that are sliced into 10 separate mini apps (what I mean are 10 releases of a puzzle game, where each app is a single image, instead of a single app with 10 images available).

    Yes, its legal but its pretty shady and in my opinion is starting to give the App store a pretty sleazy look when I'm browsing around.

    ACK! This tells me that some devs are going to start manipulating the new ranking system. Not that it would be hard (if the speculation here is correct).

    So ... here's what we know for Trenches:
    1) Trenches moves around right about 2AM Pacific time
    2) We can't pull sales trend information since "the fall"
    3) We've had a quick update to Trenches in submission since Monday ... still reporting as Waiting for Review

    What might make sense is a massive server crash the night before "the fall". Apple has (temporarily) lost some sales data and can't re-plot the Paid charts without it. "The fall" represents their "fix" until the data can be recovered. Please ... please ... be the reason and all we're waiting for is a server or two to be delivered by FedEx. I know I'm wrong ... but it's hope! Hope! ;)

    Things just got fixed. Massive changes everywhere. Some devs won. Some lost. And some didn't change at all.

    Quake confirmed

    My app (previously down 25) is now up 7, probably lost some steam because of the lack of exposure since 2am on Feb 2.

    wtf... just when the dust had started settling.

    So did they switch back to the old algorithm? Our app jumped up quite a few spots a few hours ago?

    I noticed it about an hour ago. Seems to be back to normal, with some adjustments for the instant sales some apps received.

    We just dropped about 10 ranks.... and we didn't move when they changed it before... just weird if you ask me.
