toy model: throughput multiple = 1.423 ÷ relative cost
One block: 15.64 tokens per pass15.6
Paired: 22.25 tokens per pass ÷ cost
Drag the knob around the dial (or tap A or B). The tokens-per-pass gain stays fixed at 42.3%. Only the bill changes.
Toy model with cost as the only variable. From One Block Ahead, averaged over ten benchmarks: tokens per pass 15.64 to 22.25 (+42.3%), throughput +16.3%. The 1.22x and 1.42x marks are the post's arithmetic on those averages, not numbers from the abstract. The 16 and 22 dots are illustrative stand-ins for tokens.
