I've been a RW subscriber for about 2 months from January to March 2019.  I've noticed that while backtesting from 20-30 years to today seems to show a benefit to the program long term, the short term results of most of the strategies haven't outpaced the SP500 results lately, and in many cases fell well below the return.  When testing from Nov 1, 2018 to present, it's hard to find ANY that have shown to be superior to the SP500!  Which screeners have people found that will protect us from the inevitable market correction which will occur?
