The relationship between CFR and CTR with the moving percentile from 200 observations and their power law approximation =200k/CTR0.85 . The percentile lines correspond to probabilities 0.9, 0.8, 0.7, 0.6, 0.5 and 0.4 from top to bottom. The three-segment linear approximations are shown for p = 0.9 and p = 0.7. The inset shows the dependence of the power law coefficient k on the probability p of percentile. For CTR below grey dotted lines, there are 33 and 60% of all data. The black dotted lines denote the positions of the median and the third quartile of CFR for all data
