a K/D of 41.69 - is this possible??

    I haven't seen any forum announcements about removal of KDR, don't know why you're taking his word for it. What Higby posted is that they are going to try to emphasize score rates over KDR. I don't see how that would improve the game even combined with other things, but whatever let's see what happens.

    Rofl. That's just sad.

    Makes non twitch players feel better I guess.

    Keep embarassing yourself. Let me untangle the mystery once and for all with the help of some colors:

    73+19 / 19+73 = 1

    I'll give you credit for producing some excellent mathematical gibberish, though. Keep it up :)
  5. Eric Smith

    Colors don't make wrong math right.

    And again, that's not how fractions work. You do not add numerators together then add denominators together. When adding fractions together you need to find common denominators (remember that from, what, 5th grade?). Or, to make it simple, you can convert to decimal (which spreadsheets do for you quite easily).

    Quite simply you're doing it all wrong. But, please, keep adding colors and making yourself look the fool. It amuses me.

    He can't be serious.

    Theres only one division. You're presumably thinking of what you do when you've got multiple independent fractions to add up, which is not the case here. By order of operations, we need to take the sum of all kills first, then the sum of all deaths, and only then can we perform the necessary division.

    His formula is written and interpreted as follows:

    (73+19)/(19+73) which gives the solution of 1. Any calculator, mathematical program (e.g. MATLAB), or even Google will give you that answer.
  8. Eric Smith

    Yes, because that's how you calculate an average value for multiple fractions. You add up multiple independent fractions (or decimals) then divide by the total number of variables you're working with to get an average. That is the actual definition of "average."

    His formula is wrong. We're finding averages here. In no math operation that I know of do you bother adding the numerators together then add the denominators together, then divide the resulting sum numerator by the sum denominator. And that very definitely isn't how you find the average value of multiple fractions.
  9. Xale

    Yes, which means we need to take the sum of all kills and sum of all deaths. The K/D ratio eliminates the raw values needed to attain a correctly weighted average.

    We can't take individual's K/D and average that, because each individual has an inherently different 'weight' in the equation.

    Allow me to demonstrate.
    Player 1: 20,000 / 10,000 = 2
    Player 2: 10,001 / 20,014 = 0.5 (close enough)
    Player 3: 14 / 1 = 14

    We end up with some very very messy results here.
  10. Eric Smith

    No, we don't. We are finding the average of all K/D ratios, not the ratio of total kills to total deaths on the server. The question that was asked was "how do we wind up with an average K/D ratio above 1 on a single server" not "how can you have more kills than you have deaths on a single server." If you're going to find an average K/D ratio of all players the first thing you must do is to actually average all of the K/D ratios together.

    It is perfectly possible to have a closed server with only 10 people on it and have 9 of those people with K/D ratios above 1 and to have total kills <= total deaths.

    1. K/D: 2/1
    2. K/D: 2/1
    3. K/D: 2/1
    4. K/D: 2/1
    5. K/D: 2/1
    6. K/D: 2/1
    7. K/D: 2/1
    8. K/D: 2/1
    9. K/D: 2/1
    10. K/D: 2/11
    Total kills: 20 Total Deaths: 20. 9 players have K/D of 2. Average K/D therefore is above 1 even if the ratio of total kills to total deaths comes out as 1/1.
  11. Xale

    Because, again, you've not applied any weighting. 1-9 are "worth" significantly more in your equation than they should be.

    Its like taking the average broadband speed of Sweden (lets say 40mbps) and US(lets say10mbps) and saying that the average user's broadband speed is 25mbps. Yet Sweden is a country with 8 million citizen, and the US over 200 million. Quite obviously, the average is NOT going to be 25mbps, but less.
  12. Eric Smith

    Nobody asked about a weighted average. The question was purely about the average. The point is that it's quite possible to have an average K/D above 1. It is also possible to have the majority, even the vast majority, of players able to maintain a K/D above 1 simply by having a few players with very low K/D ratios.
  13. Xale

    It was, implicitly.
  14. Eric Smith

    If you say so.

    A KDR of 1 is ideal, if you want to really match up balanced fights. That's how an automatch system in a RTS works --- the issue is not as much your win/loss % as what level of play you can break even at.

    Obviously a FPS is different (especially a MMO FPS), but this is still a bad metric to determine player quality. Of course, people smurf in RTS games too, so I think the stat ****** will always be with us. Some people feel good winning a grueling fight against the odds, some people feel good winning a mismatch, some people feel good looking at their profile stats through exploits.

    I don't think any game has really figured this out, it's just the curse of online anonymous gaming.

    Even if K/D gets removed, Daddy remains a cheater and he should be banned. We just have less documented evidence.
  17. Slyguy65

    Nah seriously he is neck beard liberator

    DVS delrith is same way.
  18. Turiel =RL=

    Nice comment by someone playing on a different server. Daddy is flying a Mossie 99.9% of the time.
  19. GaussianGamer

    Yeah, sometimes seems unfair. My gunners KDR is going up up up, and mine is going down down down...but I still have a lot of fun piloting, and thats what counts in the end :)

    K/D Ratio is a totally worthless stat in a game like this. There are those who sacrifice themselves for their team, such as Medics going into harms way to rez people, or engineers sitting at a bombarded tank and repairing it as they die. Or the Light Assault who storms a room full of enemies to disrupt them so the rest of their crew can ambush them. K/D takes none of that into consideration and sets the non-team players up on a pedistal.
