I looked at the link but did not see the #'s you mentioned. It could be Trulai's high/low ratio's of current values and/or the crime statstics reported in the area. I like the 'spotcrime' reports from 11live also called the Rowson Report. Watchdog is another good source for looking at crime in a specific area. You can set up an address and have the local crime reports emailed to you to see whats going on around you. Very helpful, I use it alot.
