Percentage errors on fitted parameters obtained from Monte Carlo simulations for uniform (unfilled boxplots) and optimal (filled boxplots) protocols at different SNR levels. The optimal protocol produces unbiased and more precise estimates for all the parameters considered: BPF (blue), ${\mathrm{T}}_2^{\mathrm{B}}$ (orange), and k _FB (green). Improvements are consistent at every SNR level, including realistic scenarios for spinal cord imaging (SNR < 25). Estimation of ${\mathrm{T}}_2^{\mathrm{F}}$ is on the other hand more precise for the uniform protocol.
