What is the minimum required to maintain a Day Streak and is the day counted from midnight in local time? For example If I test my study list it is a test of 10 questions. But if I Test one of my notebooks it is usually fewer than ten questions.  Will a test on a Notebook with only one question still count towards the Day Streak? I guess I could experiment but I don't want to lose my current streak!!
