Tyglik's method is nice in one respect because it makes the spiral in one segment. The same can be done using Schbeurd's point array if you set the rotation angle to 360 x # of turns required for spiral. and then connect all points with a curve. the drawback is when you need many turns in the coil spring, then picking all those points can be very time-consuming and Moi has no method to undo if you pick the wrong point. I would hate to pick 300 points, and make a mistake on point # 298 ! :)
