Ed,

I have to agree with you. Market fluctuations are volatile and your examples explain why.

I've often wondered if someone (not me) with a background in math and/or statistics could come up with an algorithm which would allow actual sales figures to be input by others to help keep track of averages. I know this presents other issues such as the validity of public versus private sales but if we could easily document public sales, for instance, we might have a better read on the market. I cannot believe any ONE person is capable of completing such a task so a forum with a submission form for actual documented sales might help. An idea for the form might include an eBay listing number entry or other auction ID entries that would automatically eliminate duplicate submissions.

I know... blah, blah, blah. I think I'm done now.
