How long can you keep Wu's

How long can you keep downloaded woo’s for before borkley re issue them and you dont get credited with it as a result

you get Credit at every time, and when the WUs are 6 Months old,

but

there was a Thread in the Berkeley forums

about the timelife of WUs, it was a few months ago…

it was said

if an WU is older then 6 Days and not returning to Berkeley this WUs were send again, it was going in the stats bot not for going to search for ET, this WUS were rejected

As far as I know there is no limit. A WU is sent out to several clients, so all WUs are crunched by several people. This provides a means of corroborating the results and makes sure no WU is lost.
