Demands on my time are becoming excessive. I put together as much detail as time permits and posted it to my web page.

On the page titled detail comparison I show a comparison of detail that strongly suggest that the metrics are from a 3 d construction either virtual or a model and clearly stated that. The purpose of the page is for the reader to decide for themselves so state my opinion that the A20 claim fails and present my findings.
At my first evaluation I thought the metrics were authentic but now I think they are constructs. Why, some people have more time and money than sense appearently.
Its still an interesting rock and would like to see better views but expect they will confirm rock.
