<p>[QUOTE=&quot;Robert Ransom, post: 7431917, member: 97872&quot;]The learning process here is not tough. The issue you brought forth can have many causes, in this case it is the movement of material and what caused that movement is speculation initially, followed by analysis of result and proximate cause. In most instances an answer is forthcoming, yet some become an opinion because there is no definitive response.. Answers to all questions will not be found here, IMO. Stick around and keep asking.[/QUOTE]</p><p><br /></p>
