According to CNN news on TV, the number of KIA is over 50 now sicne May 1st.
But, this article says that there were 29 killed on June 10th, about 40 days after GWB claimed “major” hostilities ended.

Thus, at that time it was about .65 killed a day.
Now, on June 18, the number was 51, just 8 days later.

This would equate to 22 in 8 days as reported by these stories. That is 2.8 killed a day.
If you average it out, 51 were killed in 49 days. That is about 1.05 a day.
In the “major war”, from March 20 to May 1st (according to GWB’s timeline), 137 Americans were killed. That is a rate of about 3.5 per day.
Thus, in the last 8 days, it has been about par for the open conflict, but the overall rate since the GWB claim of victory is about 33% of the “open hostilities” rate.
That’s the best I can do. However, if the recent increase is a trend, that post GWB rate may increase demonstrably.
This does not count the wounded, which I would estimate is at least double given the stories I have seen about injuries in an attacks without fatalities.
