The erraticity behavior observed at NA27 experiment can be readily reproduced by pure statistical fluctuations. Applying erraticity analysis to a high multiplicity sample is recommended and the method is improved at very high multiplicity case as well.11 pages in Latex 3 figures in 3 separate PS filesHigh Energy Physics - Phenomenologytext
