Zestimate changes on subsequent requestsi have a simple little script that calls the API and lets me see a few properties.http://www.greer.org/cgi-bin/zillow.pyhowever, what i have noticed is that the data changes on subsequent request sometimes. i can load the page, then hit refresh a few times and the number change, then maybe they change back. any ideas what may be happening?
