Being a younger advocate looking to be more tech savvy than the competition I've had quite a bit of interest in DSR however so far it's not been the indicator I had initially hoped for. The issue really lies within the time lag of information and as such I don't rely on it for purchasing decisions.
Also, I can be out every weekend seeing how many bidders are at auctions and over a few weekends understand the market more than watching and plotting the DSR scores. It is a useful indicator for areas that I cannot reach in person though.
That being said, DSR is more of a short term market swing indicator. At the moment, low interest rates are having an effect across the market broadly, so it's more interesting to see anomalies (big spikes) and then trying to work out what is the reason for a strong upswing and if there's any fundamental basis behind it. Ultimately property is a pretty slow game so it's better, in my opinion to look at other indicators like changes in employment or population growth before DSR.
