Hummm I thought it would be more intuitive
Never mind....
Here is an example: You are looking at a coastal merchant (22.7 metres mast) through your scope at 6x zoom and see this:
The top of the mast reaches the "100" mark (In the attack scope that would be the "10" mark, not that divisions there go 20 by 20, not 10 by 10)
You can calculate the distance quickly with a mental formula:
22.7 x 1000 = 22700
22700 / 100 = 227 (Distance it would be at 1,5x scope zoom)
and then multiply by 4 (Because you are in high zoom) to get a result of 908 metres.
Or you can look at the table and find the result like this:
The table is setup to be conceptually similar to what you see through the scope, i.e. the leftmost colum matches your scope divisions. The higher the mast on your scope, also the higher you go in that column. Then you simply slide right till the proper mast heigth column, in this case 23 metres (Rounded up 22.7 metres).
This method is way faster than browsing through the recognition manual to find a match and also allows you to make estimates based on funnels, deck, bridge, etc. heigth. If you have a printed manual with silhouettes, this method is the best possible one
