Counts for the {{TOTAL}} cataloged records, calculated live from the dataset. Head-family charts use the head_family field only; free-text head descriptions are never parsed.
Rows per head_family value. Each value is its own bar; nothing is rolled up into an “Epson total”.
Rows per verification_status, grouped by its leading wording (the catalog shows each record's exact status)
Desktop (up to 14″) vs. commercial (15″–25″) vs. large format (over 25″), from the width text
Counts represent rows in this catalog, not units sold or market share.
Head-family values are based on manufacturer or dataset claims. Only records with verified head status should be treated as independently confirmed.
