There is also a general recommendation that control circles and connecting lines should be edited to avoid obscuring any important details that might end up under the purple print.

In this particular case a straight line would have gone through the control 23-24 area, obscuring lots of stuff, so just deleting that part of the line would have been OK, except that this might have looked like you were supposed to visit one of those two controls on the way: Making a bent/curved section of the connecting line which passed over the same place as on the map, but with straight lines pointing in the correct direction for most of the leg would have been best IMHO.
