MSSQL TSQL Wymagające ciągłe grupowanie osi czasu - sql-server, tsql, analityka, partycjonowanie, oś czasu

Chciałbym osiągnąć następujący wynik wObraz. Zwijanie ciągłych zakresów w pojedyncze wiersze w MSSQL. Przykładowy kod poniżej, prawie dostałem go do pracy, chociaż myślę, że jest całkiem nowicjuszem. Myślę, że mam używać lead / lag i partycjonowanie, ale nie wiem, jak to zrobić.

Przykład Wynik
