Approach for the treatment of variability within the results

Number of replicates (n)	Multiplication factor (k)
4	1.6
5	1.2
6	1.0
7	0.92
8	0.84
9	0.77
10	0.72
11	0.67
12	0.64
13	0.60
14	0.58
15	0.55
16	0.53

Values of k were calculated assuming an underlying normal distribution as an approximation for variability and random sampling.
