Table 7 Mean pore center-to-center distance, standard deviation (S. D.), and % coefficient of variation (% C.V.) of four pores, taken from fingerprints obtained from the right thumb of four individuals on sticky side of adhesive tape (using method described in (iii)), recorded on ten consecutive days, show % C. V. to be within and/or near the normal acceptable level (with 5% confidence levels in analytical work), thereby demonstrating the reliability and reproducibility of pore inter-distance for matching fingerprints
