Recently in hep-ph/0605035 and hep-ph/0608138 , we have shown that primordial inflation can be embedded within the Minimal Supersymmetric Standard Model , while providing the right amplitude for the density perturbations and a tilted spectrum which matches the current data .
In this short note we show that the model predicts a range of spectral tilt , 0.92 \leq n _ { s } \leq 1 , depending on deviation from the saddle point condition .
The spectral tilt saturates the lower limit when the saddle point condition is met .
On the other hand the upper limit can be achieved for a slight deviation towards the point of inflection .
The running of the spectral tilt remains small , and the amplitude of the temperature anisotropies remains in the correct observational regime .
