How these comparisons work
Every mouthpiece page lists two kinds of matches, kept separate because they carry different authority. Manufacturer-declared equivalents are the comparisons brands publish themselves. Similar mouthpieces are calculated here, from published specifications.
The calculation starts from the inner rim diameter and adjusts for cup depth, backbore and cup profile, scoring each pair from 0 to 100. Only pairs that stay close on all four dimensions reach a page's top five — and a score never replaces trying a mouthpiece, it tells you where to start looking.
Specifications come from manufacturer catalogs and published spec tables. Where a maker does not publish millimetres, which for some brands is a deliberate choice, the record carries an “estimated” badge and stays out of the scoring.
