The Zestimate calculation method was revised in June this year and all numbers were recalculated from 2006 forward.
Zillow Announces Zestimate Improvements
There was no archiving of the previously calculated numbers.
The numbers from 1996 through 2005 are still the previous method, but still not the original method as one major revision had occurred at the beginning of 2008 as well.
Zillow has indicated that they are working on some other revisions, and once finalized, they will be replacing all the calculated numbers from 1996 forward.
The intent is to track the market as close as present technology allows them; not to make a history of calculation methods and method changes.

Zestimate graph is wrong
When I view the "zestimate chart" I see that the plot does not reflect all values that have been reported (by Zillow) for my home. It just shows a steady downward trend. In fact - in the past year or two, my home's vale has been as high as 410k ACCORDING TO ZILLOW.
Why is this not shown?
Disappointed homeowner,
