I forgot; Canie's out of town until Monday.

Chris, there is no good way to plot these numbers. Too many.

So I made tables, one for each area. I divided the days from 1973/1/1 to 2005/12/31 into 30 day slots and counted mags within each slot by unit of mag.

There are 401 such groups, mags from 4 to 10 possible.

Suggestions?
