Having a look at aioe's innreport:

Incoming articles seem to be less than 1000/hour, 15000/day for a 
full-text feed.
1000/hour is less than 3 articles per 10s.
Like you say, we could advise admins to look at their daily reports and 
adjust the time limit accordingly.  The question is how will they choose 
the number of articles in a transaction (30s for about 9 articles, 60s 
for 18...).
