I agree that the period the benchmark was run for was not sufficient for a more accruate estimate the benchmark should take longer (say 1 minute plus) and be run at an appropriate time. In the past I have run such tests using a scheduled job (say hourly) over a week to give an indication of when the system best copes with it.
All Benchmarks are indicative and never give the whole story and you are right to point that out. But when we have no other way of testing the code (ie use Black box X or Y) then they do give us hints as which methods to investigate further.
Benchmarking psudo-random samples is also useful when the whole dataset is massive.
Hope it Helps
