2013: TWO WEEK "HIT COUNT"

I closely monitor the daily, weekly and monthly progress of this website. With over 650,000 visitors, many of them repeat visitors who add to the count, I find a very strange trend in the daily visit count as seen in the table above. I wish I were a statistician. I would try to figure out the very interesting table above which shows the number of visits that have been made to this website over the past two weeks. Note the highlighted numbers revealing 1,000-plus  visits and their frequency, separated by two days of under 500 two day entries. "tis indeed a puzzlement and I am sure there is a logical explanation for the strange uniformity of daily hit counts.
