There's no harm in combining them. If we have a good friend or colleague whose code or predictions consistently work or often win, we can combine them with our own results and predictions. However, we still need to do careful research and consideration to determine the final outcome.

In my experience, I had a close friend who always shared his predictions, and they were always right. And when I didn't follow them, I felt regret. And after a few such incidents, I ended up following his predictions several times by doing in-depth research, incorporating my own predictions, and if I felt his predictions made sense, I would use them, which sometimes worked. Because whatever the reason, we still can't avoid losing, and nothing is truly consistent.
