 ## Considerations for Using the Data
 
 ### Bias, Risks, and Limitations
-
-- **Duplicate files:** Some flight logs appear multiple times with `(1)` or `(2)` suffixes; users should deduplicate before analysis
+- **Time zone:** IMPORTANT! The timestamps are in UTC, add +3hrs to synchronize with local Kenya time.
 - **Unit inconsistency:** Altitude and distance measurements are in imperial units (feet, mph)
 - **GPS accuracy:** Position accuracy depends on satellite visibility and may vary
 - **Timestamp accuracy:** UTC timestamps depend on drone GPS time synchronization

 ### Recommendations
 
-- Remove duplicate files before analysis
+- Convert to local time (+3hr) to synchronize with timestamps derived from SRT files
 - Validate GPS coordinates for outliers or erroneous readings
 - Consider converting units to metric for consistency with other datasets
 - Cross-reference `flycState` values with DJI documentation for interpretation
