This instrument has three numbered scales. Two are for time/distance/speed calculations. The third is an ordinary 1-10 proportional divider scale. On this scale are three marks designated N/K (N over K), S/K and N/S. The S/K I discovered designates the setting for the "Golden Ratio or Section". QUESTION: What do the other two marks designating? Any answers, responses, advice to this seemingly vexing question most welcome! Many thanks.
