Drifts 13: comparison of analysis 04 and 12

[DavorJ]

Here is a compiled pdf of plots from #51 (left) and #57 (right). They are ordered from worse to best according to #55.

The red curve in the left plot and the black difference curve in the right plot follow mostly the same pattern.

Sometimes they seem less pronounced on the left side such as here;

But this is mainly because the scale of the y-axis is many times larger on the left plot, which results in a compressed view of the pattern. Both are actually telling the same: that in this case there is some seasonality in the series.
