Good division options in 1/16, 1/32, 1/64 and 1/10, 1/20 scale, 1 /100. But why did you label the 16/32 tick as "32" and the 10/20 tick as "20" and so on? The answer is that these are markings for increments per inch, not divisions, but this is an error waiting to appear during a momentary distraction. Arrr!
