I suspect many have measured it in the lab at one point or another= but published data or solid archival data would be helpful to get a handle= on that (one of several) technical issue.=20 Thanks, Dave David A.

Do not click links or open attac= hments unless you recognize the sender or understand the content is safe. On top of the technical specs issue there is the issue of variability in fi= t for individual users. I suspect this may overshadow published frequency = response in many cases. Any ideas on how to control for that?
