The dangers of working on a live system. I'm trying to wedge in a new feature -- please bear with me.

When unreserving an exponent the server will not give you the same exponent right back. OK, not a new feature more of a bug fix.

Hm, might this be related to something I just noticed when submitting the results for M96312169?
I don't know what exactly happened there as I can't see the assignment history.
For me this looks like the exponent has been reassigned to me... or I messed up the worktodo file.

Default Crazy amount of GHz-Days???

Looks like someone is submitting a crazy amount of GHz-Days of work on the website using trial factoring. and the GHz-Days number on the server for today is just going crazy.

Hmmm...one of the fastest GPUs at 4,000 GhzDays/Day would take about 1800 years to complete that much factoring on that exponent; 900 years on the last bit level alone. And since as far as I know TF can't be parallelized even 100 such GPUs can't save time.

Unless there was a Delorean involved.

All of the Anonymous results from 2^72 onwards should be deleted.

Everyone take one TF class, or a small portion of the search space. Should be no problem to parallelise. I'm not saying that happened here though.

Could be some new QC that we are unaware of yet.

The GHz-Days values are all fixed but the PrimeNet Graph is still not fixed

Surprise! I added those at some point when I was having way too much fun with the Google graph API.

The data comes from a table of info generated daily and I'll have to manually re-run it for that day to clear out the bogus stuff.

All but one graph cover 180 days. What's the reason for that one covering only 30 days?
