Turbi...you seem to try to be contentious to get a response at times. Not all claim to be experts and value the learning experience offered by others. Arthur has been a contibutor over the years and without speaking for him perhaps prefers to share the learning experience by asking what he considers to be pertinent questions. Anyone can throw up an hypothisis and risk ridicule or be accused of ramping. There are not too many experts so we contibute what we can and hopefully continue the learning cycle. Perhaps don't look for opposition or concensus, just add what you can and take whats available.
