"Flipped the map and studied it for a while before finding any course overprinting at all, and there were 15 controls! Very small circles and numbers, light grayish purple course overprinting"
We experience this in the US from time to time and yet it seems avoidable with what technology offers. With both OCAD and Purple Pen as I recall, it's easy to make contrasting overprinting and correctly sized (or exaggerated if needed) circles. There are those maps with a lot of black (buildings, rock features or other black symbols) where it could be a challenge to make the course readily visible. I recall one in upstate NY - rock features probably over-mapped. But still, "plan ahead" for those
creating fun-to-use maps.
