I'm attempting to draft a pair of trousers according to Robert Doyle's The Art of the Tailor book.
In most of the drafting instructions there is a term used called "scale", but it doesn't refer to what it is being scaled against. I've re-read the introduction several times to look for what exactly this means (scale from side length? scale from hip width?), but I'm hoping someone who has encountered this before can point me in the right direction of what this means.
Attached is the corresponding diagram, and these are some of the sample instructions given with the term "scale":
3 from 1 is 1/4 scale
4 from 3 is 1/4 scale
7 from 4 is 1/6 the scale
