I would say that now we are looking at something like the beginning of February for the 25% scale data challenge. There is still significant work to get there, but we have made some progress in the time since the review. Usual caveats about schedule uncertainty apply. -- Mark On 12/04/2013 02:35 PM, Sandy Philpott wrote: > Dear Mark, David, Graham, > > Now that we've gotten past the 12GeV computing review, we'd like to > get more specifics on your expected timeframe for running the upcoming > Hall D data challenges.
