In the fast offline QA Lanny pointed out that it seems sector 4 has 
fewer hits and this has been the case since Monday.
After today’s QA-meeting I got a root file with all the  the information 
with various information and looked at
1) charge per pad/row
2)cluster charge per pad/row
I focused on row 39 which has two region from rdo 3 and rdo 4. From 
physics point of view they should have same #hits and charge per pad , 
in average.
The file is from run 25283030 in FastOffline,

The attached file has some additional comments , discussions, and plots

Thanks to Gene for providing the complete QA root file.
