As many people (including peppy) know, the current scoring system is highly flawed and inaccurate. Currently, there is a working system that most people find to be extremely accurate for rating scores, and that is the ranking system, pp.
It's hard to list all the reasons why this would be better than the current score system. A better question would be: Why not? Well, let's list some advantages of this system first:
1. It would make it so that scores wouldn't get beaten by a "worse" play anymore. People won't be able to easily beat 95% DoubleTime scores with Flashlight or Hidden+Hardrock. However, people will be able to beat their old HDHR or FL scores with new DT scores (which is a problem I'm currently having with some maps, that I can't beat my old HDHR scores because my DT accuracy is too low, despite the fact that the DT scores would be worth 2x the pp!). This also means that less skilled players can set scores with HDHR and not be afraid that a low accuracy DT might not be able to beat it in the future (the only reason I haven't HDHR'd Remote Control, for example), which would actually result in more accurate rankings.
2. It would more accurately represent what most people consider to be skillful. A lot of the time, scores that are ranked 1000 with the current system would in fact be high up in pp, perhaps in the top 50 of the map. Most people don't care to see low skill Hidden or HardRock scores in the top 50 when somewhere way below there's a DoubleTime with a nearly full combo which blows all of those plays out of the water.
3. If pp were to implement the three stats (aim, speed, accuracy) which tp has implemented, it could even open up a possibility to have 4 separate scoreboards on each map: Overall, Aim, Speed, and Accuracy, and the game could save the highest score a player has set for each scoreboard. This way, all players could show what they're truly capable of for each stat; a lot of the time a 95% DoubleTime+Hidden score might be worth an extremely high amount of pp because of the speed and aim required, but isn't worth much in terms of accuracy. With this system, a player could not only play that map with DTHD, but also with HDHR to get a high accuracy score as well.
There are a few disadvantages to this system, though, those being:
1. It would jumble the ranks around enough that a good portion of many scoreboards would have plays which lack replays, at least until those plays are pushed down by better scores.
2. If pp were ever to update its calculations, it could affect (possibly significantly) the placement of scores on the leaderboards. However, as far as I know, no significant changes have been made to either tp or pp in a long time, so I don't think this would be too much of an issue.
3. Any scores which were set in the past which didn't beat their highest score with the current system, but would have with the proposed system, obviously wouldn't be counted. This could cause a lot of issues with players asking that some of their scores be placed into the leaderboard because of the fact that the only reason they currently are not is because they were set before the system was changed.
In my opinion, the pros far outweigh the cons. If anyone has anything else to add, please feel free to post!
Edit: Because people keep asking, there are two reasons why mods can't be buffed or nerfed to more accurately represent skill. The first reason is that because mods don't literally multiply your score exactly, it would be impossible to recalculate old scores. This was one of the main arguments against my previous suggestion. The second reason is because a flat bonus on map-changing mods (such as DoubleTime or HardRock) doesn't work or make sense in terms of rating how difficult a play really is. Not all maps will be 1.12x more difficult with DoubleTime; some will be less, and others much more. That is what the star rating system is for.
Edit 2: Me and likely most of the supporters of the thread would be completely fine with there being an alternate "pp" scoreboard, so long as it's possible to set this scoreboard as the one viewed by default, and so long as high scores for both "pp" leaderboards and "score" leaderboards are saved.
