7 and boost means that each of those 7 options have 3 more movement options to them... so those 7 are actually 21 options. if you have advanced sensors there is the option to move before or after so that number jumps to 42.
Not actually 42. Left Bank 1 + boost left is the same as boost left + left bank 1. Same for straight and right. bank left boost right is the same as boost left bank right. etc. So it's probably more like 34 maneuvers.
