My theory comparing Germany & England: 1065/66 begins the High period because 1) Henry I's minority ends (1065) in Germany, Italy, & Burgundy, starting a new age in the Empire and a definite break from the "original" Ottonian/early Salian HRE. 2) Duke William of Normandy conquered England (1066), again, heralding the end of the Anglo-Saxon dynasty and beginning a new era there.
This period ends 1272/73. The fall of the Staufen was followed by the Interregnum (-1273), which forms another clear break in German/imperial history. The German throne was now contested by the Hapsburgs, Luxemburgs, & Wittelsbachs while Italy & Burgundy were lost. In England, Henry III's reign (-1272) marks the transition from Angevin Empire to "native" English kingdom, Edward I being the first king to bear an Anglo-Saxon name since 1066. Another similarity: after 1272/73, the German kings drop their traditional vassalization policy towards the eastern kingdoms and try to assume direct rule; England does the same towards the Celtic principalites.
In 1486, Maximilian I is crowned King of Germany, beginning an entirely new period in whats left of the Empire. The struggle for the throne is over: its now Hapsburg exclusively. In 1485, Henry VII Tudor ends the Wars of the Roses and again, starts a new era for England.
So, this rough comparison gives some convenient general dates for Germany & England: High (1065/66-1272/73), Late (1272/73-1485/86).
