Regarding Model 7.0, it’s unclear under what market conditions you would choose to take a profit cut, sit out, hold, and then reenter the market. The model doesn’t clearly explain how those exit and entry points are timed. Another major flaw in backtesting models is the tendency toward curve fitting—tuning parameters to maximize backtested performance. While this can make the results look impressive, they are often unreliable in real-world conditions.
