I have used their software for many years. Recent formulas are not robust because they essentially were over-optimized by the engine they use. In fact, the most successful formulas for one season are almost 100% net losers the very next season.

My formulas have performed for at least 15 years with some years obviously better than others. I have spent many years on creating formulas that work long term. My advice is to go to the formula warehouse and download formulas that were tested on years of data- not just one season. Most of these are losers after they were created, which shows they too were optimized which is another way of saying they simply were guilty of data mining.
