Do we need to take into account the internal resistance of the voltmeter when discharging the capacitor?  Why or why not?

The specific capacitance in F/g can be estimated by using both cyclic voltammetry curves atdifferent voltage scan rate and Galvanostatic charge-discharge curves. The following graphshows the charge-discharge curves of a typical MnO2 pseudocapacitive electrode. There is acharge drop in the voltage at the onset of the discharge curve (one such drop is denoted bydeltaV2). What is the reason behind it?
