My counts have been up for a couple of days now,probably just due to moving the counter. I'm going to move it back to the old location and see what happens. Currently working on direct networking of my new counter, probably a few days to go yet.
With the more sensitive tubes you really can see the difference just moving it around. I saw 10 cpm difference tidying up my shed and decluttering - I knocked the tube off the wall onto the desk and left it there. You can see the result on my userpage graph.
