Torsions in real molecular systems can be correlated, but TABS make the assumption that dihedral angles are independent of each other to allow for the counting of states based on the aggregated torsion profiles. While a small overestimation of the number of possible conformers in chains is accepted, this is not defensible when considering ring structures. A quick estimation of the overcount shows the importance of taking correlation into account for rings: Given the SMARTS pattern matching the dihedrals in an aliphatic six-membered ring, there would be three bins per bond, which leads to 3 6 = 729 possible combinations of the six bits of the TABS for the ring. However, a categorization into boat, chair, and twist boat (with the respective transition states, plus the extreme case of a planar ring) is much more accurate, highlighting why a reduction for small and medium-sized rings as well as macrocycles was needed.
