Being pool based, any good systems stop working as soon as too many people get onto them and reduce the divi's. The only things imo r to try to get longer odds than a runners real odds(hard to assess i know) and to try to get the best odds available during betting for your selections. For example 80% of roughies blow out in the last 5 minutes of betting and usually go past the fixed odds even tho prior to the last 5 minutes fixed were say $50 and the TAB was $36.
