That looks fishy to me. String::Approx::adistr returns the relative distance of a match, returning a value between 0 and 1. First, your values are outside that range. Second, nothing in String::Approx's docs leads me to believe that values from two separate runs of adistr() can be reliably compared.

When I tried it on my data-set it caused more errors than the previous method, although it did nail "source"!
