But no body's asking anybody to point out "skewed" data... I think it's *unanimous* that on skewed data, a higher stats target is needed for the skewed columns. The question is how much of a penalty the (majority of?) users with "normal" data columns will have to pay in stats/planning overhead to accomidate a blanket increase in DST for the (few?) skewed columns. I think Marks started to try and show that overhead/difference with real numbers. My (probably unsubstantiated) bias is showing, but nobody else has (yet) showed otherwise ;-) a. -- Aidan Van Dyk Create like a god, [EMAIL PROTECTED] command like a king, http://www.highrise.ca/ work like a slave.
