The timely junctions required you to approach a junction from the "hour" and depart by the "minute". So, for the first instruction, you approach from "09" ie from the West, and depart to "32" ie very slightly West side of South.
Departing gridlines in degrees : simply depart the gridline using the value of the compass number given. For the first instruction "69", leave the gridline at angle of 69 degrees from North, or roughly ENE. Leaving GS 6750 seemingly had two options. The departure angle of 207 was what was required to leave by the most easterly of the two options.
Just find a dartboard and approach junctions from the number given. For the first instruction "17", this number appears on the dartboard at the bottom between "3" and "2", so approach the junction from slightly East of South. Due to a last minute re-route to comply with Autopilot, the third instruction - "19" - was not actually required in this sequence.
