Thank you for your reply. I was interested in the OP question and apologise for not making this clear. I have now been through and read your posts, so have an idea of your opinions on the subject.
"so far noone has commented on either Scott's analysis of the logistics or mine...which is indeed confusing & frustrating considering how many posts there have been to the thread."
I admire your perseverance in the reading of so many posts!
"Any comments you have ...about the logistics...would be more a more than welcome respite from the posturing that we have been subjected to."
I'm afraid I cannot offer any useful ideas. I look for the authoritative opinions of those who have studied the subject from a professional angle.
"if however you are asking for an answer to Sher's question...I refuse to dignify it with a responce."
Understood! And I liked the following comment:
"If all goes according to plan I'll be able to do an onsite calculation sometime after the London Olympics (assuming Ragnarok is canceled of course :D )"
