 Assume R=1/5 and applying this equation, we can derive the size of notary set which is shown in the following figure.

 We give two curves to approximate the data point.
 The first one is y = 70.5 ln(x) - 264, which is the purple dash line and the second one is y = 74 ln(x) - 264, which is the green dash line.
