`` | `Utility class for extracting main thread jank statistics from the timeline (or other loggin facilities), and providing them in a common format to classes that compute benchmark metrics from this data. total_big_jank_thread_time is the total thread duration of all top slices whose thread time ranges overlapped with any thread time ranges of the records and the overlapped thread duration is greater than or equal USER_PERCEIVABLE_DELAY_THRESHOLD_MS. biggest_jank_thread_time is the biggest thread duration of all top slices whose thread time ranges overlapped with any of records' thread time ranges.`
