what a waste of everyone's time. as a manager, I can tell you that even my smartest engineers go through highs and lows in their career and there are days when they push out code like there's no tomorrow and days when they don't push out anything because you know there's life outside of work that affects them (their dog passed away or their wife filed for divorce or their daughter is sick and was taken to ER etc). An arbitrary 60 days look back makes no sense.
