With a deadline of 10 days, it is ridiculous for any cruncher to have a buffer of 10 days. With the reported concerns about the number of PV WU, I think some serious steps need to be implemented to reduce the maximum buffer.

To what you ask? I have never used more than 3 days while I am usually at .1-.3 days. I would not think of having more than 3 days ever.

I can understand that someone might not connect to the Internet very often, but can we afford, with the massive number of In Progress WU, to allow everyone to have 10 day buffers when there are a relatively small number who can only connect less than once a week? A quad core running only 6 hr NRW would have 160+ WU with a 10 day buffer. We'd need a truckload of 20TB drives to hold the PV work.
