We investigate systematically the effect of the electronic Coulomb interaction on the stochastic fluctuations (from sample to sample) in the persistent currents <I>I</I>(Φ) of mesoscopic rings threaded by a magnetic flux Φ. In contrast to our recent publication [Europhys. Lett. <B>18</B> (1992) 457], we avoid separation of impurity and interaction scattering events and we present here a comprehensive view. By this alternative procedure, we are able to confirm our earlier result, namely that 〈<I>I</I><sup>2</sup>〉<sup>1/2</sup> ~ <I>ev</I><sub><I>F</I></sub>/<I>L</I>, which is a much larger quantity than the average current 〈<I>I</I>〉 ~ <I>ev</I><sub><I>F</I></sub><I>l</I>/<I>L</I><sup>2</sup>.
