This archive contains all supporting fitting datasets, analysis scripts, and numerical outputs to reproduce every statistical result, table and figure presented in the manuscript titled Statistical superiority of a two-parameter fast-saturation model in fitting SPARC galaxy rotation curves: a comparison with \ (\) CDM and MOND. The study performs systematic phenomenological comparisons of six two-parameter coherent inflow functions under Fluid Space Theory (FST), alongside standard \ (\) CDM cored NFW halo models and fixed-\ (a₀\) MOND, using the SPARC sample of 175 disc galaxies. The rational fast-saturation function RATS is identified as the statistically optimal candidate via Bayesian Information Criterion (BIC), cross-validation, jackknife leave-one-out tests, bootstrap resampling, stratified subsample analysis and parameter boundary robustness checks. Data all figure placeholders, tables and statistical conclusions rely entirely on the numerical outputs contained within this archive. SPARC original observational data can be accessed at http: //astroweb. cwru. edu/SPARC/.
