Significant Discrepancy in Quarter-Based Data Analysis for Logged-In Visits: Seeking Insights

While examining metric reports in Adobe Analytics, I noticed a significant disparity between two scenarios. In the first scenario, I selected a date range spanning from January 1, 2022, to December 31, 2022, and analyzed Visit metrics with the "Loggedin" dimension, segmented by quarters of the year. In the second scenario, I narrowed the date range to January 1, 2022, to March 31, 2022, while maintaining the same metrics, dimension, and quarter-based breakdown. Surprisingly, despite the identical quarter-based breakdown, a substantial gap in data was observed. I am curious to understand the underlying reasons behind this discrepancy.
