For supercapacitors, we get symmetric triangular charge discharge curves with linear slope. Hence the formula C=I*t/m*V can be used. But for pseudo capacitors the charge discharge curves are no longer linear. Hence, how to calculate specific capacitance (F/g) from Charge discharge curves? Or is it proper to calculate or not?

Have attached a figure for bimetallic oxide material.

Current: 0.001746 A

Discharge time: (irrespective of linear or not): 738 s

Potential window: 1.0 V

Mass of active material: 7 mg

(ir drop is negligible)
