@JohnI when I created the spreadsheet for the DJIA, I only went to the point of having only 200pinners for the month. As I went back through the catalog I found there were a few months that surpassed that total. Those months were:

Jun '09 213 Pinners
Oct '09 240 Pinners
Nov '09 260 Pinners
Feb '10 244 Pinners
May '05 235 Pinners
Aug '11 231 Pinners

Whilst my spreadsheets only do 200 pinners, in my normally everyday use I have edited spreadsheets that the data is grab from that only have the 200 limit. I removed any pinner that was just a flyby-nighter for that month (pinned only once and was the worst placed aka DFP pinner). I still have the unedited files and maybe if I get to it one day I'll extend the limit to 300 to include all pinners. Just the amount of editing to increase the file pinner limit is a bit of work.

@Wazza3006 this is the nightly amount of pinners and the amount of times it has occurred.
