    Difficulty system...

    Since it seems that almost everyone is in agreement that the current ffr difficulty system is messed up, here's a proposal for a new one:

    NumberOfArrows/LengthOfSongInSeconds=Difficulty

    It makes sense that a song that has only 174 arrows spread out over around 1:50, like mario, would have a lower difficulty than say, One Minute Waltz, which has 1000+ arrows in roughly the same period of time.

    In general, it makes sense that the with there being more arrows in less time the difficulty increases as it is harder to see/press the buttons fast enough, and that the less arrows there are as time increases the easier it becomes to play it.

    Of course, this system would only apply to the ability to pass a song, not to full-combo it or get the highest score possible. To account for that would require subjectivity in deciding which sections in each song are placed in such a way as to be difficult to combo etc etc.

    Edit:

    Here's an example of how this difficulty system stacks up to the current one:

    Bubbleman Stage Theme, according to what the rating says, is relatively 4 times harder than Mario. (8/2=4)

    With this difficulty system, the value changes dramatically:

    (138/(60+20))=1.725 //Bubbleman difficulty

    (174/(60+52))=1.55 //Mario difficulty

    1.725/1.55=1.11 times as difficult Bubbleman is relative to Mario (not 4).

    Edit 2:

    I did some more calculating to see if anything turned up that seemed funny. The only real issue I have found so far is with Fotbb.

    It's difficulty is 13.058 according to this system, which is well above most other songs. Caprice is only 10.631 and rondo is 7.679 and uber rave is 7.489. I really don't think fotbb is that much harder than these songs, but I guess it could be. It's just easier to read with all the doubles in succession.

    Disclaimer: Of course I can't FC all those songs, I just added up all the perfects, goods, averages, and misseds, so these calculations assume that miss/boo system works accurately.

    Not quite. Bubbleman gets a low score because it has loads of blank steps.

    I think a complete re-examination of all stepfiles is in order and new difficulties should be determined. I'm going to champion such a project as the weeks go on.

      Cool idea. I would have to hear all the ratios to decide whether it works out or not but it seems like it would by the caprice, rondo, uber comparison.

        Wow thats a lot of math.

        Anyway, that would actually be a pretty good idea, as everyone knows that the ratings are off...but for once, this is one that actually makes logical sense. PM synth about this.

          Try DR (Difficulty Rating.) This is a new, math-crazy system I just invented. It's a good measure of how hard a song is to CLEAR (not to FC). To find a song's DR, do this:

          Go into SM, go into Edit for the song you want to find, and then press Esc.
          Then go to "Edit Song Statistics"
          Find the values for stream, voltage, and air and add those together
          Multiply that by the (#steps/sec)
          Multiply that number by 10 and round.

          Here are some examples:
          After Me = DR 119
          0.669 Stream
          0.789 Voltage
          1.000 Air
          (2.548 Total Difficulty Modifier)
          (4.69 Steps/Sec)
          888 Steps
          189 Sec
          * (Steps/Sec)

          FOTBB = DR 253
          1.000 Stream
          1.000 Voltage
          0.028 Air
          862 Steps
          69 Sec
          (2.028 Total Difficulty Modifier)
          (12.49 Steps/Sec)


          Revo = DR 288
          1.000 Stream
          1.000 Voltage
          1.000 Air
          166 Sec
          1600 Steps
          (3.000 Total Difficulty Modifier)
          (9.63 Steps/Sec)


          Uber-Rave = DR 125
          1.000 Stream
          1.000 Voltage
          0.247 Air
          964 Steps
          173 Sec
          (2.247 Total Difficulty Modifier)
          (5.57 Steps/Sec)


          Caprice = DR 212
          1.000 Stream
          1.000 Voltage
          0.115 Air
          1302 Steps
          130 Sec
          (2.115 Total Difficulty Modifier)
          (10.01 Steps/Sec)


          Sakura Heavy (DDR Official Steps) = DR 81
          0.665 Stream
          0.941 Voltage
          0.151 Air
          461 Steps
          99 Sec
          (1.757 Total Difficulty Modifier)
          (4.66 Steps/Sec)

          2 comments that are to be expected:
          Q) Why is After Me almost as hard as Uber-Rave?
          A) Uber-Rave is really easy until the insane bit near the end.

          Q) FOTBB is harder than Revo! But its DR is lower!
          A) It is not harder to clear. It IS harder to FC. Any button masher can clear FOTBB. Revo is way harder to read.

          Comments? I might expand on this formula.

            I like the second method better as it figures in a chart's groove radar. However, difficulty kind of flucuates from person to person as air and chaos are really the only items that would mess me up. Stream, freeze and voltage are really easy for me but that may differ for someone else. However, yes, that is much better than the current system. Do you think there is a way to simplify the ratings from the 0-300 range. Maybe 0-30=a 1 rating; 31-60=2 rating; etc. Or would it be more effective as is?

              It's just more effective as it is.

                  Well, like i said in another post, i think what you see on the screen at any given point should be the basis of difficulty.

                  For isntance, "Computer dreams" shouldnt be "very easy", because there's at least two parts where there's more than 4 arrows flying your way. More arrows=more difficult. For people who suck at this game (Hi!), that's where they'll falter, lose thier combo, and mess up. "Very easy" should connotate that ther should be no more than say, 4 arrows on the screen at any one time, no matter if teh rest of teh song is less than 1 arrow per second.

                  Though i do agree that the length of the song is a factor, as well. I'm just sayin that if someone can get a decent amount of perfects, then they should beable to go into a "very easy" song and get a decent score w/out having to worry about hell combos (pressing more than 6 buttons within a second)

                      I just want to add that, conversly, "Bubbleman stage three" is NOT a "very difficult" song. It should be "standard" at BEST. It's infinitly easier to both clear and get a good score on, as oppose to say, the ff7 boss theme, which is a mere -misleading- "difficult" (Should be a "very difficult" or [edit]challenging at the very least)
