As I wasn't really been paying close attention to the discussion that lead up to the new rating system (see official VTES web site), I was wondering: -What are the advantages of this particular system as opposed to the old one (I'm not saying that there aren't advantages, I just don't know what they are)? -Are all the old rating being wiped out putting everyone at zero, or are they being converted somehow?

The V:EKN currently maintains no ratings, so there are no old ratings to wipe. Before the current stat system, there had been a numerical rating system. But that was dropped some time ago. -- LSJ (vte...@white-wolf.com) V:TES Net.Rep for White Wolf, Inc.

There is some sort of rating system on the VTES web site. Maybe those ratings are "stats". Maybe they are "ratings". I don't really know the difference, which is why I was asking the question in the first place. Whatever those stats/ratings are, that are currently on the VTES web site. Are those going to have any impact on the new system, or is the current system going to be wiped out, and everyone is going to start from a zero point? Thanks, -Peter

Those stats do not translate into an 18-month rolling points accumulation system. The actual tournament reports from the previous 18 months may be used to provide the "initial" point accumulation under the new system, however, as resources permit. [ quoted text not captured ]

I don't really know the > difference, which is why I was asking the question in the first place. OK, first terminology. (Not suggesting you don't know this, Peter, but just pointing it out for discussion purposes for everyone's benefit.) "Rankings" = an ordered list of players, beginning with 1st (best) and on down to Fred (worst). (Well, sometimes it feels that way...) Usually, people are only interested in the top twenty list or the top fifty list or whatever. The list is ordered by each player's rating, usually contingent on some minimum number of results in order to be on it at all. "Ratings" = a number intended to give some approximate idea of how good each individual player is. Thus a player's skill "goodness" number. (At least conjectured as such. Whether it is or not is always opinion.) "Statistics" = any number calculated from recorded results. May be interesting or not, depending on your point of view. May measure skill "goodness" or not, depending on your opinion. So originally - years ago - we had a system of ratings and rankings based on an "ELO" ratings system, originally used in chess and picked up by the DCI for use in Magic, modified for use in a multiplayer game. The number generated is intended to measure skill level by comparing your current number with the current ELO ratings of the other players in your current game, estimate how likely it is you'll beat each player, and then adjust each of your ratings based on how the game actually came out. (I.e. you get a smaller boost for beating a lower rank player and a larger one for beating a higher ranked player. The losing player loses precisely the same number of points that the winning player gains - so it's a zero sum calculation.) One problem with that system was that its constants were very poorly chosen, resulting in wild results that fluctuated all over the place. If you won three or four straight games, your rating would take off. If you got ousted without a victory point several times in a row, a high rating would plunge to below average. Had better constants been chosen, the ratings might have been much more meaningful. As it was, they were useless. There was also a logistics problem caused by the necessity that tournament results needed to be entered in order. According to WW, this was driving the volunteers insane. No sane volunteers = no ratings/ranking system of any sort, so ELO had to go. This led to the current system of statistics that you see on the website right now. Contrary to what Scott is saying, they are using one of those statistics (I believe it's game wins divided by games played) as an unlisted rating with which to rank players. I believe I also recall there being some tie-breaker, such as victory points divided by games or something but I'm not sure. Since there's no correction of any sort for the difficulty of competition, I've always felt this system of ranking was always meaningless. Apparently I'm not the only one, because last month Steve Wieck and others brought forth a system very similar to what's posted (not sure if it's exactly the same having not examined the two proposals rigoursly) under the new web page's link to "Rating System" for discussion on the Prince's conclave. Despite my rantings advocating an improved ELO system instead, White Wolf has chosen to go with the system they've posted. There was also some discussion about how to rate large tournaments vs. small and continental championships vs. regional qualifiers vs. "mundane" tournaments. So there you have it: the history of ratings in VEKN. My feelings about the system proposed is that it undoubtably will give advantage to players who play more tournaments, despite the sliding limit of 8 tournament results contributing to each player's rating number. Some feel this is good, as it will encourage more participation in tournaments which is true. However, to some extent it will also reflect the number of tournaments players CAN attend since the number of convenient, close-by, and timely tournaments varies widely by a player's location. This will certainly affect how many tournaments each player attends, no matter what his level of enthusiasm for the game and for tournaments is. Still, it's an improvement over the current system. That's a good thing. > Whatever those stats/ratings are, that are currently on the VTES web > site.

I suspect every will start from a zero point but I don't know. Someone else will have to give a definitive answer to that. Fred

The "rating" (GWpG) is listed on the player page, actually. That is indeed the stat that is used for rankings currently. [ quoted text not captured ]
