Inferring Chart Constants

There are two primary methods currently in use for inferring chart constants. It is advisable to first understand how Potential is calculated before understanding these methods.

Fresh History Method

Developed by choka_noah, deprecated since v3.0.0

This method relies on the convention that Play Rating = Chart Constant when Score = 9,500,000.

  1. Create a new account.
  2. Play the same chart 3 times in a row and try to score as close to 9,500,000 on each of them.
  3. Multiply your Potential by 10 to obtain the Chart Constant of that chart.

Explanation

This method exploits the formula for calculating Potential, as detailed here.

  • By playing the same chart 3 times in a row on a new account, we have 3 Play Ratings under Recent Entries, and 1 Play Rating under Best Entries.
  • By scoring 9,500,000 on each play, we ensure that all 4 Play Ratings have the same value as the Chart Constant.

In this situation, the formula for calculating Potential becomes:

Hence, when we multiply the Potential by 10, this yields the Chart Constant.

Example

Chart: Dandelion [FTR]
Recent Entries
  Trial 1: 9,501,391
  Trial 2: 9,501,390
  Trial 3: 9,501,385
Best Entries
  Trial 1: 9,501,391
Potential
  Trial 1: 0.43 (+0.43)
  Trial 2: 0.64 (+0.21)
  Trial 3: 0.86 (+0.22)

Therefore, Dandelion [FTR] has a chart constant of 8.6.

Note: dropdead's Past chart has a very low note count of 44, so it is impossible to score close to 9,500,000.

This method is simple to understand and perform, but is impractical since it requires creation of a new account for every chart.

Since v3.0.0, all repeated entries in the recent 10 entries will not stack with old entries but rather replace them, rendering this method useless.

Step Method

Developed by robert_cpp.

This method uses the formula for steps gained in World Mode and Play Rating in reverse.

  1. Select the Partner with highest STEP stat and activate as many multipliers as possible (optional but increases precision).
  2. Play the chart on World Mode (Track Lost is allowed).
  3. Check Score and Steps Gained.
  4. Calculate Score Modifier from Score (see page for formula).
  5. Calculate Chart Constant with the formula:

This method requires no explanation since it purely relies on the formula, but is complicated due to the presence of numerical errors. For this reason, it is better to perform this method using a spreadsheet rather than by hand.

Numerical Errors

The displayed values for Base Steps, STEP stat and Steps Gained all have numerical errors in general. They usually have many decimals but are rounded to one decimal place. For this reason, the Chart Constant might have an error range greater than 0.1, and the error margin needs to be considered.

An error margin for the Base Steps can be obtained from the rounded Base Steps, Steps Gained and STEP stat, all which can be read from the game directly. Selecting a Partner with high STEP stat helps to reduce this error margin, which reduces the Chart Constant's error margin as well.

Since the introduction of Legacy chapters in v1.7.0 and Boost in v2.4.0, multiplying the Steps Gained generally reduces the error margin regardless of the selected Partner, hence increasing precision.

Spreadsheet

robert_cpp's original spreadsheet is available here (does not allow grade EX scores), and an extended version by GKWS is available here. A copy of it can be saved to your own Google Drive for personal use. Simply fill in the blanks in the 'Input' section and it will attempt to derive the Chart Constant at the 'Output'.

Example:

Chart: carmine:scythe [FTR]
  Score: 9,562,787 (AA)
  Base Steps: 10.1
  Steps Gained: 20.7
  STEP Stat: 102
  Base Steps (Lower): max(20.7/2.04, 10.1) = 10.147
  Base Steps (Upper): min((20.7+0.1)/2.04, 10.1+0.1) = 10.196
  Chart Constant (Lower): 9.524490036
  Chart Constant (Upper): 9.649682062

Since the only chart constant between the lower and upper bounds is 9.6, carmine:scythe [FTR] has a chart constant of 9.6.
