In my previous posting above, I calculated that the magic number would be achieved on 28th December 2016. This posting is a timely adjustment just to keep my prediction on track. Thank you for your indulgence. I will check again on 8th December and if further adjustment is required I will intervene as needed. Please do not get overenthusiastic because I would hate to have to delete some of your postings (especially some of those dodgy ones signed GUEST.)
