I do not know how much time (or articles) there is between checkpoints.
I had one yesterday:
Apr 29 10:04:47 news innd: tomate.motzarella.org:639 checkpoint seconds 65533 accepted 298 refused 2774 rejected 2 duplicate 0 accepted size 633978 duplicate size 0 rejected size 7675
And I believe the 298 accepted articles are the right number at 10:04:47
(since I had 224 accepted articles the previous day, until 04:15).

Yes, you're right.

Probably because I receive a few articles in that news server.
I had a checkpoint, though :)

I do not thing such changes should be made.
Indeed, it is a problem inherent in innreport. I believe an innreport
temp file should be created (in /var/log/news/innreport.channels for
instance) wherein, during the process of news.notice, it will log,
as it is already done with the CURRENT innreport, server:channel when
it is initiated.
The file should be written at the end of the process of news.notice.
It contains all the channels still opened (with their last checkpoint).
The next day, we see, when there is a closed connection, if there
already was a line in innreport.channels. We just substract the
counts and we have a once-count number of articles.
I hope my explanations were clear enough. Do not hesitate to tell
me in case they were not.
