Pārāśarī counts seven movable significators (BPHS Ch. 32); Jaimini counts eight, admits Rāhu by reverse degree and adds the dāra-kāraka (Upadeśa-Sūtra 1.1.10). Both tables are computed from the same reference instant — 1990-01-01 06:00 IST — so the structural difference is visible row by row. Compute your own at /chart.
Rankings are degree arithmetic, nothing else. No prediction is attached to any kāraka.
Rāhu walks the zodiac in the retrograde sense, so JS 1.1.10 reckons it by effective = 30° − deg-in-sign. The 7-system (BPHS Ch. 32) omits Rāhu entirely.
In this chart: raw 24.74° → effective 5.26° → rank 6 (Putra-kāraka).
दार-कारकः — the eighth role
In the 8-system the planet with the lowest effective degree — the final rank after sorting — is the dāra-kāraka, the spouse-significator. The role has no Pārāśarī counterpart; the 7-system stops at GK (jñāti).
In this chart: DK = Budha (बुध) at 2.03°, effective 2.03°.

BOTH SCHOOLS IN THE CHART RESPONSE
The full 8-kāraka assignment ships in the /chart response alongside the BPHS 7-system, both computed from the same substrate.
