The reason the most recent tape was split was around March 05 is not because we have a huge backlog of data - it's because we couldn't afford any more DLT tapes and stopped recording data around that time. Plus all our old DLT drives are broken - we have only one left up here at the lab that reasonably works - that's what I use to read these old data tapes.
I think I have about 50 tapes left in my pile to split. At the current "burn rate" this should last about a month.
However! We are releasing SETI enhanced, which should slow everything down, and this current set of data should last many more months - hopefully long enough to get the new data recorder down to Arecibo and get that all working.
And! Due to one reason or another we do have many tapes that were split and sent out but we have only about 10% scientific return - so we may throw those back into the pipeline if we otherwise run out of workunits to send out.
