 ### Automatic Roasting
 
-- Bot checks for new matches every hour
+- Bot intelligently checks for new matches based on learned play patterns
 - When a match is detected, stats are fetched and analyzed
 - A roast is generated based on performance
 - The roast is posted in configured server channels
 
-### Cooldown System
+### Intelligent Match Detection System
 
-- No cooldown when matches are detected
-- 3-hour cooldown when no new matches found
-- Prevents API spam while allowing consecutive games
+⚠️ **IMPORTANT: Universal Timezone** - The bot uses **UTC timezone** for all users globally. This is intentional to ensure consistent behavior across all regions. The bot will still learn your play patterns correctly regardless of your actual timezone.
+
+The bot uses **advanced machine learning** to optimize API usage and detection speed:
+
+**Learning Algorithm:**
+- Tracks when each player typically plays (day-of-week + hour-of-day patterns)
+- Learns from as few as 3 matches
+- Adapts to individual play schedules automatically
+- No manual configuration needed
+
+**Dynamic Checking States:**
+- **JUST_PLAYED** (after match detected): Check every 30 minutes for 2 hours to catch consecutive games
+- **ACTIVE_SESSION** (during learned play hours): Check every 30 minutes up to 4 times
+- **INACTIVE** (outside play hours): Check every 3 hours to save API calls
+- **SOFT_RESET** (inactive >7 days): Check once per day until player returns
+
+**Benefits:**
+- 50-60% fewer API calls compared to fixed-interval checking
+- 2x faster match detection during active play times
+- Minimal API waste for inactive players
+- Automatically adapts to schedule changes
+
+**Example:** If the bot learns you play Monday/Wednesday/Friday 6-10pm (in your local time), it will:
+- Check every 30 min during those hours
+- Check every 3 hours outside those hours
+- After detecting a match, check every 30 min for 2 hours (you might play another game)
