I think you want a control chart. A good place to start might be http://en.wikipedia.org/wiki/Control_chart. Even if you don't actually graph the data, understanding the math behind control charts might help you with your analysis. Wow. I think this is the first time I'm actually used something I learned by sitting though those stupid Six Sigma training classes :-) -- http://mail.python.org/mailman/listinfo/python-list
