降级中滑动时间窗口的个数是1 ，会不会导致统计不够精准以及统计粒度太粗

版本 1.8

The issue only identifies Sentinel version 1.8 and includes an image; it names no file, test, or entry point. Start by locating the degradation sliding-window implementation and its tests, then determine whether a single window reduces statistical precision or makes the granularity too coarse. Done means documenting the behavior and agreeing on a concrete correction or confirming that the current behavior is expected.
