After some reflection on what I said on the thread and some of the questions that followed I have learned that the decision to write what I did was a bit rash. In any controlled experiment there are numerous factors that need to be adequately communicated in order to interpret the data properly. In this instance I have commented on the results but cannot provide any of the conditions that generated them, as such none here are able to draw their own conclusions and I have done you all a disservice. I have deleted my original posting. Please accept my humble apologies and understand that I cannot comment further. This was not well thought out on my part.
