When you perform an autorotation, the first thing is: "RPM rotor"... So when you put the pitch down, you "normally " desynchronize RPM/NG UP or DOWN....And so, you check
the freewheel...Better if your RPM rotor are higher than your RPM NG In turbine engine, when you perform an autorotation descent with engine runing but desynchronized ( free wheel runing normally ), and then you put the turbine on idle, i admit you feel a little increase of the rate of descent. What else ,
