Pp Rework Calculator

Predict changes to your osu! global rank and total performance points.

Play Rank	Original Weighted (pp)	Reworked Weighted (pp)	Difference

Formula: $TotalPP \approx \sum_{i=0}^{n-1} (PlayValue_i \times (1 + \frac{Factor}{100}) \times 0.95^i) + BonusPP$

What is a pp rework calculator?

A pp rework calculator is a specialized tool used by rhythm game players, specifically within the osu! community, to predict how changes in the performance points algorithm will affect their global standing and total skill rating. Since the developers frequently update the math behind “pp” to balance different skill sets like aim, speed, and accuracy, players often see their scores buffed or nerfed overnight.

Who should use it? Primarily competitive players looking to understand if a recent or upcoming pp rework calculator update will benefit their specific playstyle. A common misconception is that a rework “takes away” skill; in reality, a pp rework calculator simply adjusts the numerical representation of that skill to match the current competitive standard.

pp rework calculator Formula and Mathematical Explanation

The core of the pp rework calculator lies in the weighted sum of a player’s best scores. In osu!, your best score is worth 100%, your second best is worth 95%, the third 90.25%, and so on. The formula follows a geometric series: $0.95^{(n-1)}$.

The pp rework calculator applies an adjustment factor ($R$) to individual play values before summing them up with the standard bonus PP. The derivation looks like this:

Variable	Meaning	Unit	Typical Range
Total PP	Total performance points on profile	pp	0 – 25,000
$i$	The rank of the play (1st, 2nd, etc.)	Integer	1 – 100
$W$	Weighting factor (0.95)	Ratio	0.95 (fixed)
$Factor$	Percentage change from rework	%	-15% to +15%

Practical Examples (Real-World Use Cases)

Example 1: High-Rank Aim Player

Imagine an aim-focused player with a pp rework calculator input of 12,000 total PP and a top play of 800 pp. If a rework targets aim spacing and results in a -4% nerf, the pp rework calculator shows their new total dropping to approximately 11,520 pp. This helps the player realize that while their number is lower, their relative rank might stay the same if other aim players are nerfed similarly.

Example 2: New Player Speed Buff

A newer player has 2,000 PP and a top play of 150 pp. A rework favoring high-accuracy speed plays introduces a +3% buff. Using the pp rework calculator, the player sees a gain of roughly 60 PP. This motivates them to focus more on the skills being rewarded by the new algorithm.

How to Use This pp rework calculator

1. Input Current PP: Enter your total performance points from your profile page into the pp rework calculator.
2. Define Top Play: Input the raw value of your #1 top score to help the calculator estimate your score decay curve.
3. Adjust Impact Factor: Move the slider or enter the percentage change expected from the rework (e.g., if aim is being nerfed, use a negative value).
4. Review Results: The pp rework calculator will instantly update the graph and the estimated new total.
5. Analyze the Table: Look at the “Play Rank” table to see how much each of your top plays contributes before and after the change.

Key Factors That Affect pp rework calculator Results

• Weighting System: The 95% decay means that changes to your top 10 plays matter significantly more than changes to your 50th play.
• Bonus PP: This is a flat value based on the total number of scores. Most pp rework calculator models assume this stays constant unless the rework specifically targets the bonus system.
• Playstyle Bias: Reworks often target “meta” maps (like short jump maps). If your profile is full of these, the pp rework calculator will show a steeper decline.
• Rank Density: In lower ranks, a 50 PP change might move you 10,000 spots, while in the top 1,000, it might only move you 10 spots.
• Difficulty Scaling: Changes to how Star Rating (SR) is calculated directly feed into the pp rework calculator as raw value shifts.
• Accuracy Sensitivity: If a rework increases the “OD” (Overall Difficulty) scaling, your high-accuracy plays will see a larger buff in the pp rework calculator outputs.

Frequently Asked Questions (FAQ)

Can the pp rework calculator predict my exact new rank?

It provides a high-probability estimate. Since rank depends on every other player’s score, the pp rework calculator uses historical density data to approximate your new position.

Why did my PP go down but my rank stayed the same?

This is common when a pp rework calculator shows a “global nerf.” If everyone loses 5% of their PP, the leaderboard order remains largely unchanged.

Is the Bonus PP affected by reworks?

Usually no. Bonus PP is capped at 416.67 and is based on the quantity of unique maps passed, not the quality of the performance.

How accurate is the decay model in this pp rework calculator?

We use a logarithmic regression model to simulate a standard player’s top 100 plays. For players with very “top-heavy” or “flat” profiles, actual results may vary by 1-2%.

What does “Weighted PP” mean?

Weighted PP is the value a play actually contributes to your total after the 0.95^n multiplier is applied. The pp rework calculator focuses on these values.

How often do reworks happen?

Major reworks occur approximately once or twice a year, though smaller hotfixes may happen more frequently.

Can I use this for other rhythm games?

While designed for osu!, the logic of the pp rework calculator can be applied to any game using a weighted geometric mean for its ranking system.

Does the calculator account for “unranked” maps?

No, the pp rework calculator only considers scores that currently contribute to your official performance profile.
