Re: FFR Skill Rank System

If only there was a way of determining what songs had which patterns.....

Re: FFR Skill Rank System

There is. Just play every song and record what they had. Only problem is it'll take way too long.

Not really (not about the length). It's extremely subjective and will never be accurate. I find trills, rolls, bursts, speed absolutely no problem. Jumpstream? Friggin hard. It will always be diverse and inaccurate. Inaccurate since even if you find a medium, there will always be high deviation because of huge varying opinions.

Re: FFR Skill Rank System

Okay, well, I've created a new and highly improved version of my program although it still fails to take many things into account as mentioned previously. But I think this would probably get about 98% of people into their correct divisions if we could determine numbers to be the cutoff of each version.

The program:

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class SkillTestV2 {
public static void main(String[] args) {
new SkillTestV2().start();
}
public void start() {
List<Score> theList = new ArrayList<Score>();
Scanner console = new Scanner(System.in);
while (console.hasNextLine()) {
String line = console.nextLine();
if (line.startsWith("Average Rank:")) {
break;
}
Scanner s = new Scanner(line);
if (!s.hasNext()) {
continue;
}
s.next();
if (!s.hasNextInt()) {
continue;
}
int difficulty = s.nextInt();
String current = "";
if (s.hasNext()) {
current = s.next();
}
String songname = "";
while (s.hasNext()) {
songname += current + " ";
current = s.next();
if ((1 == current.length() || current.length() > 6) && (current.endsWith("0*") || current.endsWith("5*") ||current.endsWith("0") || current.endsWith("5"))) {
break;
}
}
if (!current.endsWith("*")) {
continue;
}
int perfects = s.nextInt();
int goods = s.nextInt();
int averages = s.nextInt();
int misses = s.nextInt();
int boos = s.nextInt();
double val = goods + 1.8*averages + 20.0/275*boos;
theList.add(new Score(songname, difficulty, (int) val));
}
// iterate over the list and get the best scores
Score[] best = new Score[10];
int[] weights = {10, 9, 8, 7, 6, 5, 4, 3, 2, 1};
int[] goods = {2, 5, 10, 15, 20, 25, 30, 35, 40, 50, 75};
for (int i = 0; i < 10; ++i) {
best[i] = new Score("You lose", 1, 9999); //really bad score
for (Score s : theList) {
if (s.difficulty > best[i].difficulty && s.goods <= goods[i]) {
best[i] = s;
}
}
theList.remove(theList.indexOf(best[i]));
}
int total = 0;
for (int i = 0; i < 10; ++i) {
System.out.println(best[i]);
total += weights[i] * best[i].difficulty;
}
System.out.println("Total score= " + total);

}

public class Score {
public String songName;
public int difficulty;
public int goods;

public Score(String songName, int difficulty, int goods) {
this.songName = songName;
this.goods = goods;
this.difficulty = difficulty;
}

public String toString() {
return (songName + " (" + difficulty + ") " + goods + " goods.");
}
}
}

Output with my level ranks:
0 (piano version) (66) 1 goods.
K8107 (65) 4 goods.
For FFR (67) 8 goods.
Gynandromorph (66) 15 goods.
Starwolf (72) 20 goods.
Romance in the Club feat. Liquido (70) 18 goods.
Undiscovered Colors (70) 26 goods.
Midnight Dragon (69) 19 goods.
Summer Time Perfume (69) 37 goods.
Caprice (73) 50 goods.
Total score= 3723

Very simple to use and now uses a player's 10 best scores. Just click run, copy and past your level ranks (use select all) into it, and it produces the output.

Edit at 3:50am on 7/21: Improved to this:
0 (piano version) (66) 1 goods.
K8107 (65) 4 goods.
For FFR (67) 8 goods.
Starwolf (72) 13 goods.
Romance in the Club feat. Liquido (70) 18 goods.
Midnight Dragon (69) 19 goods.
Undiscovered Colors (70) 26 goods.
Exciting Hyper Highspeed Star (69) 33 goods.
Summer Time Perfume (69) 37 goods.
Caprice (73) 50 goods.
Total score= 3748

I'm quite the noob when it comes to programming. Does this calculate average rank of songs played?

Re: FFR Skill Rank System

Best 2 or fewer * 10 +
Best 5 or fewer * 9 +
Best 10 or fewer * 8 +
Best 15 or fewer * 7 +
Best 20 or fewer * 6 +
Best 25 or fewer * 5 +
Best 30 or fewer * 4 +
Best 40 or fewer * 3 +
Best 50 or fewer * 2 +
Best 75 or fewer
And each must be a unique song, and I can easily make it maximized so that you get the highest possible score it can give you with forcing each to be a unique song.

ffr, where we need ranks, stats, etc... for everything

Re: FFR Skill Rank System

What skill range is supposed to represent each division? It gave me 2,686 (I'm mid-high D2)

I think I'm probably doing something wrong by trying to run this program in command prompt with jdk :S

Re: FFR Skill Rank System

I have been doing that, but where do I paste my ranks

[arcnmx]

Re: FFR Skill Rank System

Oh, into the prompt. On Windows it's right-click -> paste or something?

[rushyrulz]

Re: FFR Skill Rank System

Yep that did it thanks

The Bird's Poisoned Bathwater (79) 1 goods.
44 Edit (82) 4 goods.

EDIT: Hijacking this post to give some thoughts, since this isn't a doug-skill-thing-support-thread.

Weighted best scores aren't the worst way to to judge people. It's inherently flawed as long as combo scoring exists and wouldn't actually work as an actual ranking system since it ignores everything but your best 10 scores. However, it probably would give a nice rough indicator for things like tournament placement purposes. Not for ranking though, it's too transparent and one-dimensional.

Of course, that's only if you use difficulties as a factor to indicate skill, which I really don't recommend to begin with.

I wouldn't be against simply using song difficulties as a major factor in ranking, even if it discards details such as skillsets. They're unimportant in the bigger picture as long as the system rewards things like consistency more than anomalistic scores.
