Double the input, then choose one expansion
A fixed cumulative 14006 BC anchor gives two alternative landings in the extended genealogical display.
Input: 9660 = 2 × 4830
14006 − 9660 = 4346 BC
Calculated endpoint of the doubled input.
9660 × 70/69 = 9800
Opens the extended Adam carrier: 4206–4136 BC. Increase: 140 years.
9660 × 25/23 = 10500
Noah 3576–3506 closes; Shem 3506–3436 opens. Increase: 840 years.

Hold the cumulative MT Adam Year-6 Moses/Nisan coordinate 14006 BC fixed. The unexpanded 9660-year input has the calculated endpoint 4346 BC. Multiplying 9660 by 70/69 gives 9800; 14006 − 9800 = 4206 BC opens the Matthew-side extended Adam carrier 4206–4136 BC. Alternatively, 9660 × 25/23 = 10500; 14006 − 10500 = 3506 BC closes Noah 3576–3506 and opens Shem 3506–3436 in the same extended display. The gains are 140 and 840. The expansions are alternatives, not successive steps. The extension before Abraham belongs to the comparative model; Matthew’s Gospel itself begins its genealogy with Abraham.
