For No. 3: Hello Steve, that is exactly the problem. <code> 1853 # cons xff steps rows 1854 AVERAGE 0.5 1 1008 1855 AVERAGE 0.5 12 4320 1856 MIN 0.5 12 4320 1857 MAX 0.5 12 4320 1858 AVERAGE 0.5 144 720 1859 MAX 0.5 144 720 1860 MIN 0.5 144 720 </code> So I have only 33 hours in the small granularity. That explains also why the steps are later 12 times more. If i create a database with a small granularity over 1 year, will it work correct or will I get problems? Thanks!! You save my day. Martin
