Now lets consider the FS E depicted in Clause Samples

Now lets consider the FS E depicted in. Fig. 7 created using the next intervals: E¯1 = [2, 5] and E¯2 = [3, 5], E¯3 = [4, 6] the y2 level there are 2 intervals which have to be added. Note that in this example with 2 intervals, it can be simply considered as the length of the intersection of both intervals divided by the length of the union.
