Anyone who accepts that a competent measurement technician, competently

Hi Owen,

Questions, emphatic competency, and reasonableness all in the space of
one sentence. I can see the well where you drew the literary "wax

I will leave you to arguing wether Walt's observed 5% reduction is of any
value.

The follow-on discussion between you and Walt obviously reveals
sufficient value.
