Zeta, thanks for just "popping in". When you start a thread about a subject, unless you want to try to babysit and keep everyone on topic, its going to evolve into something that you might not have thought of. In this case, it looks like everyone wants to try to be funny instead of discussing something they felt they had already discussed. And truth is, many have here. Also of note is that while there are a few "armchair climbers" here (I prefer "deskjockey" myself), there are also some people that climb alot more than you have and could actually could give you some useful insight.
That said, it doesn't even appear that you have read the ANAM 2007 that is in question? Why don't you go buy a copy (the money goes to a good cause!) and READ it! There you will find an analysis that is done as well as can be with the actual information at hand. Those folks do a great job. Then, if you do have any SPECIFIC questions that are not answered there after you do this, then come back and ask them here.
It will be much smarter than coming here and asking a group that has already rehashed and rehashed this issue.
As for the rest of you, spray is done in this thread.
Thanks.
