I assume we all feel activity declining for the last decade. I did the math.

Again without Classic league as it distorts the view.

Zooming in on more recent years.

Here's NNN league activity. Some data is inaccessible unfortunately. I have attained conflicting versions of data, so there are two plots.

These graphs as an attachment:
