Just to point out, if I may, that a set of posts on this thread that finally led to my walking away seems to have been deleted. The moderator comments sum up the character of these deleted posts well IMO. This is not, by any means, a complaint about the deletion. I just wanted to clarify events for anyone reading the thread later. I didn't leave immediately after Steve Gardham's sensible post of 4.54, and I wouldn't want people thinking that particular post was the straw that broke the camel's back.
