How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Goal target = 100, Current progress = 0, Timeline = 12, Hours per week = 10 = 7 input(s) provided
  2. Calculate Achievement probability
    Achievement probability = min(95, max(5, rawProbability * 100))
    51 = 51
  3. Calculate Weekly progress needed
    Weekly progress needed = gap / max(1, timelineWeeks)
    8.33 = 8.33
  4. Calculate Daily progress needed
    Daily progress needed = weeklyProgressNeeded / 7
    1.19 = 1.19
