Hello Sheffield has availability above 95% in nagios tests and atlas analysis for every month during this 2012 (and in 2010 and 2011 as well). In quarter reports there is a parameter "Average SLL untargeted ATLAS test performance (UK test)" which is 87% for Sheffield for the last Quarter. I'm wondering what does this parameter reflect? AFAIR there was already discussion on this topic but "Average SLL untargeted ATLAS test performance (UK test)" is still in Quarter reports.
