Portfolio Re-Structuring/25% CAGR quality-growth for next 2-3 years

Donald sir, Hitesh sir and other seniors. I read this thread from the beginning.
I also found this Momentum based ETF rotation - Amazing backtested results - Need Reviews

Please share your viewa on this, as technically it is a very good idea, but I am not sure, why no one is follwing that thread and also I want to know if any senior is following such strategy long term…
