How does the method of the Two Calculators compare to the method based on assured portions (Yaqin) when dealing with a daughter, a son, and a Khuntha?

When applying the assured portion method to a case involving a son, a daughter, and a Khuntha, the son receives 16/40 (two fifths) with certainty, and the daughter receives 4/40 (one fifth) with certainty. The Khuntha receives 16/40 (one quarter) with certainty. The disputed six shares are divided, with the Khuntha receiving half of them (three shares), totaling 13 shares. The son, claiming four shares, receives half (two shares), totaling 18 shares. The daughter, claiming two shares, receives half (one share), totaling 9 shares. This contrasts with the method of the Two Calculators, which results in a denominator of 40 after multiplying the male scenario (5 parts) by the female scenario (4 parts) and then doubling it (20 multiplied by 2). Under the Two Calculators, the daughter receives 9, the son 18, and the Khuntha 13, meaning the Khuntha receives less than one third of the total 40.

The method of assigning disputed portions after the certain portions (which aligns with the Manzilin method in many cases) differs from the view of the Two Calculators in specific instances, as demonstrated by the differing share allocation for the Khuntha, son, and daughter.
