Conjectured rational points on genus-two curves associated with products of consecutive integers

Let TA5T\in A_5, and let CTC_T be the corresponding genus-two curve, with r(T)r(T) denoting the rank quantity used in the source. Rational-points conjecture. For r(T)>1r(T)>1, the values of TT and the finite rational points CT(Q)C_T(\mathbb{Q}), omitting the points at infinity (1,±1,0)(1,\pm1,0), are exactly those listed in the table in the source: (2)(2) with rank 22 and points {(2,0),(1,0),(0,0),(2/3,±460/3)}\{(-2,0),(-1,0),(0,0),(2/3,\pm460/3)\}; (3)(3) with rank 22 and points {(9,±252),(3,0),(2,0),(1,0),(0,0),(18/5,±468/5)}\{(-9,\pm252),(-3,0),(-2,0),(-1,0),(0,0),(-18/5,\pm468/5)\}; (0,4)(0,4) with rank 44 and points {(0,0),(1,±29),(9/4,±5871/4)}\{(0,0),(1,\pm29),(9/4,\pm5871/4)\}; (1,3)(1,3) with rank 22 and points {(4,±6),(1,0),(0,0)}\{(-4,\pm6),(-1,0),(0,0)\}; (1,4)(1,4) with rank 22 and points {(1,0),(0,0)}\{(-1,0),(0,0)\}; (0,1,2)(0,1,2) with rank 22 and points {(2,0),(0,0),(1,±27)}\{(-2,0),(0,0),(1,\pm27)\}; (0,2,3)(0,2,3) with rank 22 and points {(0,0)}\{(0,0)\}; (1,2,3)(1,2,3) with rank 22 and points {(3,0),(1,0),(0,0)}\{(-3,0),(-1,0),(0,0)\}; (1,3,4)(1,3,4) with rank 22 and points {(4,±6),(1,0),(0,0),(25/9,±620/9)}\{(-4,\pm6),(-1,0),(0,0),(-25/9,\pm620/9)\}; (0,1,2,3)(0,1,2,3) with rank 33 and points {(4,0),(2,0),(1,0),(0,0),(13/3,±91/3),(5/3,±55/3)}\{(-4,0),(-2,0),(-1,0),(0,0),(-13/3,\pm91/3),(-5/3,\pm55/3)\}; and (0,1,3,4)(0,1,3,4) with rank 22 and points {(3,0),(1,0),(0,0)}\{(-3,0),(-1,0),(0,0)\}. The table is based on numerical computations after the authors were unable to characterize the rational points for some TA5T\in A_5; it remains conjectural.
