The exchanges with Ericsson have shown that we need to be meticulously clear in defining what we mean by that and how we measure it, so I won't post more numbers until I feel that our description is precise enough.

I also would like to see some tests which tell us where we really are.  A lot of us are engineers who like having facts, even if, as many of us realize, the comparative performance is a minor part of the debate.

I welcome Ericsson's efforts to get clarity in this area; they seem to have been working very hard to get a level playing field measure, and if you can help that effort, this would be all to the good.
