MMR Repair Deep-Dive 2025 | Fix Broken Ratings & Restore LP Gains

By the EloAscend Expert Team — Master-Challenger players with 50,000+ combined hours. This deep-dive is a companion to the MMR Blueprint. Where the Blueprint teaches system theory, this guide teaches repair practice with real case studies and advanced troubleshooting.

Cluster Navigation: MMR Blueprint = theory. This guide = practice. For advanced LP math, see LP Gain Science. For when to play, see Queue Timing.

Step 1: Diagnose Your Broken MMR (Reality Check)

Before repair, confirm the MMR is actually broken. Not all bad LP is MMR damage.

The Diagnosis Test (10 Games)

1. Play 10 ranked games (any condition, normal mindset)
2. Record every LP gain and loss (avg gain, avg loss)
3. Calculate your ratio:
   • Average Gain ÷ Average Loss = ratio
   • Example: +17 / −23 = 0.74 ratio (BROKEN)
   • Example: +21 / −16 = 1.31 ratio (HEALTHY)

Step 2: Choose Your Repair Strategy

Three paths to repair. Different philosophies, same result.

Strategy 1: Conservative (60–80 games, Low Risk)

Best for: Players with mental health concerns, first-time repair, low skill ceiling

• Champion pool: 1 champion only (absolute mastery)
• Games per day: 2–3 games max
• Target win rate: 52–54% (very sustainable)
• Queue only: Peak hours + weekends (best lobbies)
• Breaks: 1 week off per month (reset mental)

Pros: Lowest mental burnout, highest sustainability, best for long-term improvement

Cons: Takes 70+ games, slower MMR recovery

Strategy 2: Balanced (50–65 games, Medium Risk)

Best for: Most accounts, moderate skill level, decent mental

• Champion pool: 1–2 champions (main + backup)
• Games per day: 4–5 games (block system)
• Target win rate: 54–56% (challenging but achievable)
• Queue: Peak hours + some flexibility
• Reviews: 1 replay per 3 games (learning loop)

Pros: Fastest mainstream repair, balanced risk/reward

Cons: Requires discipline, moderate mental investment

Strategy 3: Aggressive (40–50 games, High Risk)

Best for: Challenger-ready players, strong mental, time-available

• Champion pool: 1 champion only (permaban-proof)
• Games per day: 6–8 games (full focus)
• Target win rate: 57–60% (very high threshold)
• Queue: Peak hours + strategic late-night (when meta relaxes)
• Data: Track every metric (macro mistakes, deaths, time to power spikes)

Pros: Fastest repair possible, highest skill expression

Cons: High tilt risk, mental fatigue, one bad week derails progress

Step 3: Execute the Repair Protocol

Choose your strategy above. Now execute week by week.

Week 1: Setup & Testing (5–10 games)

1. Lock your champion(s)
2. Play 5–10 games, observe win rate trend
3. If < 50% WR after 10: **strategy too aggressive, downgrade**
4. If > 60% WR: adjust strategy upward (you're ready)
5. If 50–55% WR: perfect, continue

Week 2–4: Grind Phase (30–40 games)

• Execute your chosen strategy rigidly
• Track LP gains weekly (watch for trend, not daily noise)
• Expected: +0.05 to +0.10 ratio per week (small improvements)
• If no progress after 15 games: analyze losses (macro errors? tilt? unlucky?)

Week 5–8: Stabilization & Acceleration (15–30 more games)

• By week 5–6, ratio should improve to 0.85+ (getting close to healthy)
• Continue strategy
• By week 7–8, expect ratio > 0.95 (HEALTHY ZONE)
• Once at 1.0+, you're fixed. Transition to normal climbing.

5 Real Case Studies (Before & After)

Case Study 1: Gold ADC — Severe Damage (Aggressive Fix)

Start Profile:

• Rank: Gold II
• LP Ratio: +14 / −25 (0.56 — severely broken)
• Playstyle: 3–5 ADCs, 8–10 games/day, late-night queueing

Intervention:

• Lock: 1 ADC (Caitlyn)
• Strategy: Aggressive (6 games/day, peak hours only)
• Focus: Reduce deaths (was averaging 7 per game)

Result (50 games, 6 weeks):

• Win rate: 48% → 58%
• LP Ratio: 0.56 → 1.05 (HEALED)
• Final Rank: Gold II → Platinum IV
• Lesson: Death reduction had 3x impact vs mechanics

Case Study 2: Platinum Mid — Moderate Damage (Balanced Fix)

Start: Plat III, +18 / −21 (0.86 — damaged), 50% WR, 7 champions, emotional queueing

Intervention: 2 champs, 4 games/day, 1 replay/session

Result (55 games, 7 weeks): +21 / −16 (1.31 — healthy), 54% WR, Plat I

Case Study 3: Emerald Support — Mental Collapse (Conservative Fix)

Start: Emerald IV, +15 / −26 (0.58), 44% WR, tilted, unmotivated

Intervention: 1 champ, 2 games/day, mental break after 1 loss, no grinding

Result (70 games, 12 weeks): +19 / −18 (1.06), 52% WR, back to Emerald II with improved mental

Case Study 4: Diamond Jungle — Boosted Account (Recovery)

Start: Diamond IV (boosted), +12 / −28 (0.43), 40% WR solo, 75% WR with booster

Intervention: Realize skill gap, downrank to Plat IV voluntarily, rebuild from there

Result: Demoted to Platinum, climbed naturally to Diamond over 4 months with 55% WR

Lesson: Sometimes demotion is repair. Ego-free demotion > fake rank with broken MMR

Case Study 5: Master ADC — Single Bad Week (Quick Heal)

Start: Master 50 LP, +20 / −17 (healthy), 1 bad week of -150 LP / 8 losses

Damage: LP ratio dropped to 0.88, but MMR mostly OK

Recovery (15 games): 1 week of focused play, back to +20 / −17

Lesson: Light damage heals fast. Severe damage takes months.

Troubleshooting: When Repair Stalls

Problem: After 20 games, LP ratio unchanged

Causes: Wrong strategy, tilting, champion not scaling, poor macro

Solutions:

• Check if you're actually playing the strategy (are you really at 54% WR or lying to yourself?)
• Review 3 losses in detail (deaths, macro timing, wave state at key moments)
• Consider Aggressive → Balanced or Balanced → Conservative downgrade

Problem: Won 5 straight but LP still +15/−25

Cause: Very severe MMR damage (e.g., +10/−30). Takes time to climb out.

Solution: Keep going. After 50 games at 55% WR, you'll see the shift.

Problem: Hit a plateau (e.g., Gold II after 40 games, stuck)

Causes: Hit real skill ceiling, or reached equilibrium MMR = your actual rank

Solutions:

• If stuck 10+ games with 50% WR: you've hit your natural rank. Move on.
• If stuck 10+ games with 55% WR: improve mechanics/macro (coaching might help)

Problem: Demoted during repair

This is OK! Demotion might actually ACCELERATE repair by resetting you to your true MMR tier.

Advice: Accept the demotion, continue the strategy. You'll re-climb within 10–20 games.

Mental Strategies During Repair

The Repair Mindset Shift

Before Repair (Wrong Mindset):

• "Why am I stuck? The system is rigged."
• "One win should put me in promos."
• "I'm better than my rank."

During Repair (Correct Mindset):

• "My MMR is below rank. I need 50–80 games to fix it."
• "Every game contributes to the repair. Small improvements daily."
• "My rank is accurate until MMR recovers."

3 Mental Anchors

1. Anchor 1: The "50-Game Commitment" — You are committing to 50–80 games of focused play. Once you accept this, each game becomes less stressful (you're not desperately trying to win 1 promo, you're investing in 50).
2. Anchor 2: "Ratio Over Rank" — Stop tracking rank. Track your LP gain/loss ratio instead. When ratio hits 0.95+, you know repair is done. This removes the "stuck" feeling.
3. Anchor 3: "Process Over Results" — You can't control wins. You can control champion pool, hours played, decision-making. Focus on process, not 7-game win streaks.

Avoiding Future MMR Damage

Once you repair, how do you avoid breaking it again?

The 3 Damage Patterns (Avoid These)

1. Loss Streak Spam: Lost 3 games in a row, kept queuing emotionally. Result: −150 MMR in 1 day. **Stop after 2 losses.**
2. Champion Spamming: Played 20 different champs in 50 games. System got confused. **Lock 1–2 champs.**
3. Elo Collapse: Was Platinum, played badly for 100 games, dropped to Gold with broken MMR. **Take breaks before collapse.**

Prevention Protocol

• Track LP ratio weekly (stay ahead of damage)
• Stop ranked after 2 losses (hard rule)
• One break per month (4-7 days off ranked)
• If ratio dips below 0.90, start mini-repair (20 games at 55% WR)

FAQ

How long does MMR repair really take?

50–80 games at 53–57% win rate. If you play 5 games/day, that's 10–16 days. If 3 games/day, 17–27 days. Mental health matters; don't rush.

Can I repair while duoing?

Not recommended. Duo with higher MMR friend pulls you into harder games, slowing repair. Wait until ratio hits 0.95+, then duo.

Should I get coaching while repairing?

Yes, if you're stuck after 25 games. Coaching identifies mistakes faster than solo analysis. Even 1–2 hours of coaching can accelerate repair by 10–20 games.

What if I demote during repair?

Expected. If you demote from Gold to Silver while repairing, you've hit a more stable MMR level. **Accept it and continue.** You'll re-climb faster than before.

Is elo boosting better than self-repair?

Elo boosting fixes rank temporarily but not MMR. After boost wears off, you'll drop back unless your own skill improved. **Self-repair is permanent.** Boosting is useful for big rank jumps; repair is for fixing broken MMR.
