We agree. But if that auto was custom tuned to optimize fuel efficiency in a manner that bore no relationship to what you could expect or use to compare with another dealers car the value would be zero.

I don't believe the TPC benchmarks are valid for any comparison purpose. They are just numbers for marketers to trumpet.

If Oracle is equal in speed to DB2 in a benchmark does that mean you can get equal performance from either with your application? I don't think so.

If two cars produce equal fuel economy you can likely take it to the bank that your experience will be, not the same, but similar.
