Field notes
The project separates calculation logic from code editions, describing each edition as its own downloadable pack with amendment and effective-date versioning. Its proposed result sheet records the formula and every input, then can be exported as a PDF for job paperwork. The page also says out-of-range inputs produce an explicit error rather than an extrapolated answer, while metric and AWG catalogues remain separate.
