Each pulse represents 10° of crank angle with the first pulse marked by cursor 1 at 170°. Reading from left to right the first gap is at 150° BTDC the next at 110°. 0/360° is 11 pulses counting to the right. The next gap is at 330° BTDC and the last (right most) gap is at 300°.The pulse at cursor 2 is back at 170°. Non VVC have gaps (according to the manual!) at TDC, 50° BTDC, 180° BTDC, and 240° BTDC.
