 ### 3.1.4 Strategies to Increase Reproducibility
 
-Many problems are environment-specific, often manifesting sporadically, especially under high concurrency. The challenge lies in addressing these infrequent occurrences, which may happen just once every few months. Increasing the frequency of problem reproduction—from every few months to every few hours or minutes—significantly simplifies their resolution.
+Many problems are environment-specific, often manifesting sporadically, especially under high concurrency. The challenge lies in addressing these infrequent occurrences, which may happen just once every few months. Increasing the frequency of problem reproduction—from every few months to every few hours or minutes—significantly simplifies their resolution.
 
 How can this be achieved? Capturing patterns in problem occurrence is crucial. For example, when addressing simultaneous failures in Group Replication that sporadically freeze views, analyzing statistical patterns reveals critical insights. These problems often cluster around specific thresholds. Adjusting lower-level communication timeout settings to align with network interruption durations enables more frequent problem reproduction. Once these critical factors are understood, the likelihood of reproducing problems increases significantly, laying a solid foundation for effective problem resolution.
