    Margin of error.

    Lets say in the last election, there were 0.5% questionable votes, or unusable/invalid votes. What percentage of the votes cast were questionable/unreadable/invalid this election? 0.4%? 1%?

    That's how you can determine it.

    If we were voting using black and white marbles in a box, it would be easy, there's no way to be ambiguous. Except that it's hella hard to count 120M marbles, and you'd need a huge box. :)

    Accuracy in this case is probably best described as "signal to noise ratio", or the ratio of properly cast to improperly cast votes (with regards to the actual content of that vote).

    I was following the exit polls throughout the day, and they weren't matching the voting results at all, until you applied the 3% or so error of margin that exit polls are supposed to have.

    At which point it became obvious that in this close of a race, exit polls are meaningless, as they can be well within their error of margin, and still not accurately reflect the outcome, since the outcome is (essentially) a binary choice instead of an analog value.

    I think these election results were well down into the statistical noise, and the results are not completely clear. It just proves that we need to further refine the voting system to make it more accurate, and to get out an even higher voter turnout.

    But if a CD wasn't going to be bought new, at retail, then the copying of it doesn't constitute an actual loss. I've receive a ton of MP3s and copied CDs from friends which were of the "listen to this!" offer. Most have ended up in the trashcan (real or virtual). Those few I actually liked, I try to buy, although I usually end up buying used anyway, because I don't have the money for retail prices right now.

    p2p allows someone to go browsing and finding interesting things, and decide if you want to own them or not. If you DON'T buy the CD, then yes, it's a loss of a sale, but if it was a CD you're weren't going to buy, as it costs too much, then it's not really a lost sale.

    The problem is that they see 1mil downloads of britney spears latest hit, and 1 mil downloads of the hit before that, and if off the same CD, claim that 2mil CDs worth of goods weren't sold, and were stolen, and that that's $36mil in revenue lost.

    When in reality, they might only have lost a couple hundred thousand sales, say (250K), for a real loss of $4.5mil.

    Which is yes a loss. On the flip side, they probably also gained some sales by people finding new artists, and buying thier CDs. The problem is that no one has any statistics for how many mp3s are kept instead of buying cds, which percentage of those would have resulted in sales had the person not already had the mp3s, how many cd sales resulted in mp3s/cds copied from friends, etc.

    I'm a volunteer FF in a small town (10K people) in a valley, we're an all-volunteer dept, and the county GIS data is crucial for us for planning purposes, but we also back it up with USGS, our own surveys of where hazmat is stored (both legally and illegally) and our own data on locations of hydrants, weight-limits on bridges, and widths of roads for getting fire engines up into the VERY narrow, tight turns around redwood trees.
