Question to the stats for sierpinski / missing values...
 
[url]http://www.sr5.psp-project.de/s5stats.html[/url]

The last table on the output of the given link shows the number of open 'n':

Open n per block(Shown upto 2.0Mil):
upper_bound amount
100000 ---------> 4
125000 --------> 32
150000 --------> 73
175000 -----> 15920
...

That is where we stand, the server gives out tests with n>150000.

When I look one table above this one on the same html-page, then I miss the 4 values for 75000>n<100000.

The table contains the following header:

kvalue|weight|min n untested|max n tested|...

There is no 'min n untested' beyond 131011.

Where are the missed tests?

Due to the fact that we had lots of test that needed recovery the stats use a filter to only show min n tested >100000.

I can't believe it. I was testing Phil's code from 150000 to 151000 on all remaining n and stopped at about 150680. I was so looking forward to knocking one off with his code and would have done so had I waited another day.
