Nelson, I think you're right on both accounts. About how a fragmented table would show up in 10046 data: there are lots of people on the list. Maybe one has the time to try it. If it takes more time, it'll show up in response time *somehow*. If not, then it's simply not a problem for the case being traced.

The whole point of Method-R (the Millsap/Goodman/Holt tuning method) is to de-mystify and simplify tuning. Eliminate the guess-work. Precisely identify the performance issue and nail it. Everyone who is willing to put in some sweat equity can use Method-R. I'm not sure how a badly fragmented table would show up in a 10046 trace file. If a table reorganization is really required, I think a trace would show excess physical io.
