Q:
What is the difference between Normal Time and Standard Time?
Normal Time adjusts average observed stopwatch time by the operator performance rating: Normal = Observed × (Rating / 100).
Standard Time incorporates Personal, Fatigue, and Delay (PFD) allowances: Standard = Normal × (1 + Allowance).
Standard Time49.98 sNormal × (1 + Allowance)
Normal Time44.63 sObserved × Rating
Average Observed42.50 sN = 10 Cycles
