As the program expands, older data comprise an increasingly small fraction of the dataset, and scores on older notes have tended to fluctuate causing some of them to lose Helpful status.
To maintain Helpful note quality as the program continues to grow, we are locking note status once a note is two weeks old. This approach allows us to optimize the algorithm with a focus on current data while persisting helpful contributions on older topics.
