This method should be used lechumra only and returns the time of plag hamincha according to the Magen Avraham (MGA).
Day in this calculation starts 120 minutes before sunrise and ends 120 minutes after sunset. This is calculated as 10.75 hours after dawn 120 minutes. The formula used is 10.75 shaahZmanis120Minutes after alos120. Since the zman based on an extremely early alos and a very late tzais, it should only be used lechumra.
