James is on the mark at a few shots an hour. Regarding the quantity of data, though, you are wise to keep in mind that monthly update findings should in general be treated as preliminary, relative to future publication. We do hope to make 2010 and earlier data available in full soon, there has been some discussion of a public repository also shared with other DPF groups, so need to get cracking there. Fourteen shots today, FYI ;-D
