I have been intermittently lurking as take a break from swimming while regrowing skin after a high speed bike crash 3 weeks ago.
I seem to have created a monster with my innocent original post! But a good monster lol. The various points of view have been fascinating. Even the apparent contradictions have been a stimulus for careful explanations, some of which have been very enlightening. There has been a lot of information to digest here. I hope I have the energy and focus to review this over and over in the future as my experience and technique improve -- currently there sometimes may be more information than I can make use of.
