The 1 method is a la Cessna and checks the controls as in the stick for full and free novement.
On the airliner the fact that you won't get your buckles caught is taken as read. What you're looking for is that as you turn the tops in elavator the control a) goes full deflection without feeling stiff or having any deadbands(think cars with knackered power steering) and b) comes back to dead centre. Same in Aileron and with rudder.
