A very simple crt.
King Piccolo's Young key has him listed with Ageless immortal due to him wishing for eternal youth. The problem is clear, the actual scan shows him asking Shenron to restore him back to when he was overflowing with power, aka his youth. He does not ask for eternal youth.
More evidence is when he fights Goku after gaining his youth, he mentions that his lifespan shortens every time he exerts himself a little too much.
So yeah, I suggest removing this part entirely. His stats and ki should simply be improved while he's Young.
