Lexicon overlap between author and dialects
This is how much the author's top 200 most frequently used words overlaps with each major dialects top 200 words
An overlap of more than 50% is a pretty good match. Because of the nature of the top 200 words, almost no-one has an overlap of more than 70%, they'd have to be writing about a really broad range of things, like body parts, working, playing, thinking, governance, and so on.
On average Scots writers overlap with English by about 27%, so this is perhaps an indication on where on the Scots - Scottish English spectrum a writer's lexicon lies.
