Many types of distributed computing applications don't due uniform
processing (and reporting on percent done) like SETI, Astropulse or Einstein
... and the biological science applications (and image rendering ones) have
taken some time to discipline the reporting of percent done.
What the BOINC Client does not do is use the hashsums of computing
applications (as sometimes they run in pairs as in Climate Prediction) to
form a local knowledge base of
-- work unit size (average, median, standard deviation)
-- work unit computation length (average, median, standard deviation)
-- completed work unit average size (average, median, standard deviation)
-- disk use (average, median, standard deviation)
-- these could be uplinked to the BOINC design groups and the projects
themselves ... as you probably have to do an SQL query to find this stuff
out
-- THE "STATS" tab is almost totally devoid of usable statistics ... and the
ones above relating to runtime are graphable and usable ...
I am not saying this will fix the wonky estimated run time problem ... only
regular application reporting to the BOINC client will ever do that.
However, the averaged knowledge from these parameters could improve it when
the daft application is not reporting.

Subject: Re: [boinc_dev] Estimated Time Remaining
Not all applications report smooth % complete. So the calculation of time
remaining involve the initial estimate as well. Given the bad information
given for both % complete and initial estimate, there is no method of
predicting how much longer the task will take that is completely right. The
most reliable appears to be to combine the initial estimate the DCF (if in
use for the project) the % complete, and the time spent already (the only
really well known item in the list) to come up with an estimate.
