The differences in the evolution of ⟨N pair ⟩ over time in the "good" and poor solvents, with the structure able to rearrange towards fully overlapping in the "good" solvent but trapped in partially overlapping structures in poorer solvents, suggests that aggregation through fewer monomers is sufficient to hold two chains together as solvent quality decreases. If partially overlapping chains are effectively inseparable, at least on the time scale of becoming trapped by further aggregation, a build-up of extended aggregates with increasing R g will occur.
