I apologise, I thought you were implying that what omalleyt 'really meant' was a perfect circle is data we can calculate

It seemed to me you were changing the question that was being asked, and a question asked implies an answer, or 'goal post'

But if you were just developing new inquiry stead building off omalleyt then I apologise and would hope to encourage like critical thinking in the future

.. Thinking on it 'goal posts'.. and 'soap box' elsewhere in this thread.. lacks a timeless quality, I really should have left it out ;P
