🎯 Objective
The Pickleball365 formula calculates a 0–100 score for each pickleball player using a transparent, performance-based system inspired by Elo ratings. It integrates match data from multiple sources (e.g., DUPR) and recalculates a consistent score based on your performance and opponent quality.
🧮 Step 1: Elo-Based Rating Calculation
For each match played:
expectedWin = 1 / (1 + 10 ** ((opponentRating - playerRating) / 400))
scoreChange = K * (actualResult - expectedWin)- •
Kis a constant (e.g. 24) that controls sensitivity - •
actualResult: 1 = Win, 0.5 = Split, 0 = Loss - •
opponentRating: from DUPR or inferred Pulse365 Measurement - •
playerRating: player's current Elo score
📊 Step 2: Adjustments Per Match
Match results are weighted using several key factors:
| Factor | Effect |
|---|---|
| Opponent Strength | Bigger delta for upsets |
| Margin of Victory | Larger win margin = greater gain |
| Match Recency | Linear decay to 0.5× at 180 days |
| Match Type | Tournament wins get +20% weight |
| Championship Match Weighting | Finals get +25% multiplier (stacks to 1.5× with tournament) |
| Activity Frequency Adjustment | Impact scales with last-30-day matches; inactivity decay ~1.5%/month |
| Location Diversity Factor | More unique venues = fuller impact; single venue reduces impact (≥0.3×) |
| Surface Adaptability Bonus | Non‑preferred surface +5% bonus |
| Rapid Improvement Adjustment | K-factor +50% boost + floor reset for breakout players |
| Volatility | New players = larger K value |
🚀 Rapid Improvement Adjustment (Streak-Based Acceleration)
Pickleball365 automatically detects "breakout" players who consistently outperform their current rating and accelerates their rating growth to prevent slow climbs.
Trigger Conditions (ALL must be true):
- • Win Consistency: Player has won ≥8 of their last 10 Pickleball365-logged matches
- • Upset Factor: ≥5 of those wins were against opponents rated at least +5 Pickleball365 higher (≈ +50 Elo)
Effects When Triggered:
- • K-Factor Boost: +50% increase (e.g., 19.2 → 28.8) for the next 10 matches
- • Floor Reset: Immediate rating boost to at least the average Pickleball365 of defeated higher-rated opponents minus 3 points
- • Conservative Approach: Prevents overshooting while providing meaningful acceleration
Automatic Expiration:
- • Boost automatically expires after 10 matches
- • No penalties applied when it expires
- • Future results drive the rating normally
// Example: Player with 60 Pickleball365 wins 8 of last 10 matches
// 6 wins against 70-75 rated opponents (+10-15 Pickleball365)
// Result: K-factor boost 1.5x, floor reset to 69.5
// New rating: 69.5 (up from 60)🧾 Step 3: Normalize to Pulse365 Measurement
Once Elo is updated, it's converted to the Pulse365 Measurement 0–100 scale using a logistic curve:
Pulse365 Measurement = round(100 / (1 + math.exp(-0.005 * (Elo - 1500))), 1)Key points:
- 1500 Elo = 50 Pulse365 Measurement (average player)
- 2000 Elo ≈ 76.2 Pulse365 Measurement (strong competitive player)
- 1000 Elo ≈ 23.8 Pulse365 Measurement (beginner)
| Elo Range | Pickleball365 Range | Player Type |
|---|---|---|
| 1800+ | 90–100 | Top Pro |
| 1600–1799 | 75–89 | Competitive Club |
| 1400–1599 | 55–74 | Intermediate/Recreational |
| 1200–1399 | 35–54 | Casual/Beginner |
| <1200 | 0–34 | New or struggling |
Introducing Pulse365™
Your game, simulated.
Pulse365 is the intelligence layer of the Pickleball365.
Using AI-driven simulation, it analyzes your match data and predicts how your style performs against different opponents, doubles pairings, and play conditions.
Powered by our multi-agent engine, Pulse365 creates digital versions of you and your competition — then runs thousands of virtual matches to uncover patterns like:
- Which shot patterns win under pressure
- How your win probability changes by opponent type
- When momentum shifts in long rallies
- What doubles combinations create the highest synergy
Your Pulse365 dashboard shows:
- •Win Probability Curve — likelihood to win sets or matches over time
- •Momentum Map — how rallies shift momentum across games
- •AI Replay — textual or visual simulations of "what-if" matchups
Pulse365 doesn't guess — it learns your rhythm.

🧩 Social vs Competitive Scoring
- • Separate rating pools: Social and Competitive
- • Social matches only affect Social Score; Competitive matches only affect Competitive Score
- • No cross-contamination between contexts
🔁 Step 4: Update and Store
Each match result is saved with:
{
"opponent": "David King",
"date": "2025-07-29",
"result": "Win",
"score": "11-8, 11-7",
"source": "DUPR",
"duprDelta": 0.10,
"pickleball365Delta": 1.4,
"summary": "You beat a higher-rated player. Great result!"
}The player's Pickleball365 score is then updated in Pickleball365.
