If you'd like, in a few days, when I have time, I can share with you some day on day numbers for various comments and the users that made them. Just let me know what strings you want me to look for and I can get it to you.

I'll extract the data for may in a day or so, then I should have full year to date if you want to track that far back.

Let me know, happy to help you identify the trend. I like data :D
