Levenshtein Ratio Rule Tester

Enter a list of value pairs to test against the lev-ratio rule. The Levenshtein Ratio measures how similar two strings are based on the number of single-character edits required to transform one into the other. The score ranges from 0 (completely different) to 100 (identical). A pair is considered a match when its score meets or exceeds the threshold you specify below. Results include both raw and normalized comparisons so you can see how normalization affects fuzzy matching.

Score formula: round(100 × (len(A) + len(B) − distance) / (len(A) + len(B)))

Pairs with a score ≥ this value are considered a match.
