How rare are one day 100+ tornado producers??

There was a question that came up on how rare is a one day 100+ tornado producer. I recently researched that going back to 2000 and there is not a day that produced over 100 tornado reports. However, there are 9 (2 day periods) that helped to produce 100+ reports. Of the 9 days 6 happen to be in the month of May. 3 of the 9 happen to occur on other months. The most recent of these events occured in April 9-10 2009.

Just May
May 29-20 2004 170 reports
May 4-5 2007 122 reports
May 4-5 2003 117 reports
May 10-11 2008 112 reports
May 22-23 2008 112 reports
May 6-7 2003 109 reports
* Note the month of May happens to be the peak month in the United States for tornado outbreaks.
