Absolute max. I would stive for is less than a week, e.g. 3-4 days.


which contradicts the first statement.
Then again if a slow computer, crunching on 1 WU for 200+ hours returns
a correct WU, whereas 2 or 3 extremely OC PCs crunching a WU in less
than 1 hour return garbage, then I would assume that the result that took
8+ days is more useful than the fast results which are useless...

OTOH I have a cache of 1 week, which allows me to continue crunching away
in case of a before seen outage...

Hold on here....  48 hours before becoming invalid?  Then how can you
simultaneously suggest a three or four day cache?  That seems
logically inconsistent, because every one of those units would be
worthless.

Your assertion about the 48 hour limit to get into the scientific
database is a bit hard to believe, because a lot of people are still
running machines that take that long to do a single unit.  If these
are all invalid that effort is utterly pointless and a waste of their
time, electricity, and all the work unit management effort at SETI
that supports these users.


this supports my statement of the PC crunching a WU in over 200 hours ;o)

Yeah, but the guys with 2.5hr/WU machines will have already sent the 2 - 3
confirming WU's that will get credit for the science, long before your unit
comes in.


and who knows, maybe those are precisely the useless results because they
have been analyzed on extremely OCed machines and return inconsistent
results.

All you'll be doing is building stats, and adding a small amount of
additional corroboration to the earlier corroborating units. Not saying
additional corroboration is a bad thing, per se, but the major 'science'
will have already been 'done'.


Yogi Berra once said: "It ain't over 'till it's over"
and with elections it's "nothing is final until all the votes are in"
and in US elections (FL) it adds: "... and the mistakes are accounted for"

so if 5 5 WUs were sent and all 5 results are inconsistent, then further
WUs need to be sent until consistent results are received.
That's the science, and not who gets their junk back faster.

Just my 2�
