Twin peaks representing the time savings predicted when using shot within shot optimization. The comparison is made between shot within shot plans prescribed at the 50% IDL (SS50%) and shot within shot plans optimized using collimator weighting and different selections of the prescription IDL (SSopt). The optimal plan provided an equivalent diameter of the prescription IDL in the axial plane, a gradient distance (factor = 0.5) no worse than 3% from the original, and a minimized beam-on time
