so for A ( algebraic difference in grades), and a (parabola constant), g1 and g2 are only numbers (no percent). For example, 4.2% upgrade, and -2.8% downgrade, when we using these grades to calculate A or a, they will be used as 4.2 and 2.8. However, when we are calculating PVC, we need to use4.2% and 2.8%?

As you know, the units are extremely important - it's possible to use feet & decimal percentage OR stations & percent grade. For instance, if you had a grade of +4% for 600 feet, these two alternatives would be: Feet and Decimal Percentage: 0.04 * 600 = 24 feet of elevation change OR Stations and Percent Grade: 4 * 6 = 24 feet of elevation change For simplicity and also for consistency with other vertical curve calculations, I recommend using stations and percent grade.
