Mean local gamma passing rates ($2\%/2\hspace{0.17em}\text{mm}$, local normalization) for the COMPASS system and mean global gamma passing rates ($2\%/2\hspace{0.17em}\text{mm}$ and $3\%/3\hspace{0.17em}\text{mm}$, global normalization to maximum with a low‐dose threshold at 10% of global maximum) for the COMPASS and Mobius3D systems. Results were extracted for all structures and locations of the 12 real VMAT plans
