These are in-sample predictions — all mixes were part of the BOxCrete training dataset. A well-fitted GP should track closely to the 1:1 line. Out-of-sample performance will be lower. Strength outputs from the model are in MPa and are converted here by ×145.038 to psi for comparison with the measured values.
