How to calculate specific capacitance from GCD if current density, mass load , time in second and window in V are given?

In a paper attached here, the author has used current density 0.5A/g, mass 0.5mg, window 0.3V and discharge tume is 45s. By using these values he has calculated C=673 F/g but when I calculate, I...

If potential window is -0.2 to +0.3, then during GCD of a supercapacitor, Discharge stop at 1= voltage less limit (voltage=-0.2 ?? is it so ?

Discharge stop at 1 Voltage less than limit it is will be -0.2 value of limit (voltage ) and Charge stop at 1 Voltage greater than limit it is will be +0.3 value of limit (voltage ) ?
