Figure 6. Creation’s endpoint pair is 4115t/4114n BC. The reflected Conquest pair is AD 1406t/1407n, with t for Tishri and n for Nisan. Each matched component spans 5520 civil years; multiplying by 25/23 gives the distinct converted measure 6000. This is not the Rounded Mirror operator. Spacing is schematic.

View the image versionTishri: Creation endpoint 4115t BC to reflected Conquest AD 1406t gives 4115 plus 1406 minus 1 equals 5520 years. Nisan: 4114n BC to AD 1407n gives 4114 plus 1407 minus 1 equals 5520. Multiply 5520 by 25 divided by 23 to obtain 6000 as a Priestly-converted measure, not the civil span.
