Crash

The method of selecting runners has taken a while to work out. I fear if I reveal my selection method, it is doomed to fail. I started using the filters I described earlier including newspaper tips as you mentioned and ranked these filters in order of importance based on results. As you said it probably won't sustain winners over the long term, so then it will be time to change the method of picking favored runners by using the same combination of filters but in a different order based on what is winning and applying these filters. As you would know, there is no hard and fast rule with systems. You have to keep moving all the time.
