I gave this topic some thought last week:

http://tools.ietf.org/html/draft-morton-bmwg-virtual-net-01#section-4.2

   ... external observations remain essential as the
   basis for Benchmarks.  Internal observations with fixed specification
   and interpretation may be provided in parallel, to assist the
   development of operations procedures when the technology is deployed,
   for example.  Internal metrics and measurements from Open Source
   implementations may be the only direct source of performance results
   in a desired dimension, but corroborating external observations are
   still required to assure the integrity of measurement discipline was
   maintained for all reported results.

This text is new and isn't agreed yet, it's my thoughts on the topic.
