The FEI Grand Prix dressage test has something called the Zig Zag. This is a very difficult movement that calls for five half passes to either side of the centerline with a flying change of leg at each change of direction, the first half pass to the left and the last to the left of 3 strides and the others 6 strides. When the rider gets to the fifth half pass they breathe a sigh of relief.
