Ditto.
I don't use a common string board, but have been making them for 25 years on an older design. Obviously you are looking for a process that will be consistent and yield perfect string lengths every time. After a while you will likely adjust a bit based on the bow you are building for. If you want your string to fit a specific bow, based on loop size, twists/inch, and desired brace height, then one string layout formula will not work for all bows. Basically, I start twisting for the top loop at 9.5-10 inches, and 8.5" for the bottom loop, for wide limbed recurves. For a narrow limbed bow, I may shade those lengths a bit, so as to make up for smaller string loops.
I get a pretty long fade in compared to some others, and although I do care about avoiding too much mass in the string I like the look of a longer fade in. As flinter says, just take it apart and redo it if it's too long.
