This page lists all songs in order of their chart constant. For more information on what a chart constant is, please see Potential. Essentially, it's an internal value that factors into how much a song affects your Potential and how many Steps you gain from it in World Mode. They are presumably based on the development team's perception of song difficulty, but as these values are hidden, they may not be.

The "method used" column is used on the Japanese wiki to indicate which of two derivation methods was used to calculate the constant. More information can be found at the JP wiki. A translation of these methods follows after the song lists.

Deriving a Chart ConstantEdit

There are two methods currently in-use for deriving chart constants.

Fresh History (choka method)Edit

This method searches for a chart constant by using the fact that at 9,500,000 score, your chart potential is equal to your chart constant.

First, make a new account. Play the same chart 3 times in a row and try to get as close to 9,500,000 as you can on each of them. The potential calculation looks like this:

 P = (Total of recent entries chart potential + Total of best entries chart potential) / 40

By this method, if the chart potential is the same as the chart constant, you'll have 3 songs in recent entries and 1 in best entries, which gives you:

 P = (Chart constant x3 + Chart constant x1) / 40 = Chart constant / 10

In other words, playing the chart three times (and getting close to 9.5 million) will give you a Potential that is 10 times the chart constant for that chart.

In order to get accurate values, you need to do this on a new account, where both the recent entries and best entries are empty. However, if you use an older account and manipulate it so that your recent entries are empty (by playing thirty short songs in a row and not doing anything), you can still derive an approximate chart constant, though it's a little wacky. In that case, you'll need to do at least 4 plays, and make sure select a song that's easy enough so the chart potential will not be reflected in best entries.

dropdead's Past chart has a very low note count of 44, so it's impossible to get a chart potential that is equal to the chart constant (getting close to 9.5 million without rounding the chart potential down or up).

Example:

[Chart] Dandelion [FTR]
Recent Entries (can have multiples of same chart)
  Trial 1: 9,501,391
  Trial 2: 9,501,390
  Trial 3: 9,501,385
Best Entries (cannot have multiples of same chart)
  Trial 1: 9,501,391
Potential
  Trial 1: 0.43 (+0.43)
  Trial 2: 0.64 (+0.21)
  Trial 3: 0.86 (+0.22)

With the play results above, the chart constant would be 10 times your potential, or 8.6.

World Mode Steps (robert method)Edit

This method searches for chart constant using the relationship between World Mode score and STEP count.

With your rank at AA or less and your STEP count at more than 2.5, if you use the score and step count, you can find the chart constant with the following formula:

CC = (9,500,000 - (Score - ((Step-2.5) / 0.004473062)^2)) / 300,000

However, STEP counts are imprecise, so you can't get a precise chart constant like this. Instead, we'll use a Level 20 Tairitsu (Grievous Lady) to find the error margin for the STEP count, then calculate a chart's constant from the maximum and minimum STEP counts:

Minimum Value = max(PartnerIncludedStep / 2.04, Step)
Maximum Value = min((PartnerIncludedStep+0.1) / 2.04, Step + 0.1)

This uses level 20 Tairitsu (GL) to narrow down the error margin as much as possible with her high STEP stat, and because there's no proof that a partner's stats are even integer values.

Please note that EX rating and higher uses a different formula that is still unknown. If you're going to use this method, get a AA or lower.

In version 1.7, with the appearence of the "Play+" feature, multiplying the gained Steps will always work regardless of your selected partner, but make sure the Step count output is at least twice the input Steps by result.

User:Darkslime has translated robert's original spreadsheet here. Make a copy of it to your own Google Drive to use. Basically, while using level 20 Tairitsu GL or Ilith, input your score, base steps, and adjusted steps, and it will attempt to derive the chart constant. Again, get an AA or lower, no EX.

  • Example
[Chart] carmine:scythe [FTR]
 Score: 9,562,787 (AA)
 STEP: 10.1
 STEP with Partner Effect: 20.7
 Minimum: max(20.7/2.04, 10.1) = 10.147
 Maximum: min((20.7+0.1)/2.04, 10.1+0.1) = 10.196
 Chart constant derived from minimum: 9.524490036
 Chart constant derived from maximum: 9.649682062
 One decimal point rounded: 9.6

Therefore, carmine:scythe [FTR] has a chart constant of 9.6.
