yesterday on the phone I had an idea for a plot that would show cohort growth at constant CGPs (constant 50, constant 70, constant 25, etc) across their time in school. showing actual growth over those reference lines would give insight here as well (two good years and one bad year is equivalent to three years of constant growth at what CGP?)
