With limited flight time I tried to figure out the quickest way for the spark to return home. I did some experiments and I found interesting results I like to share. Here they are.
First experiment - RTH
Starting point: 70 meters high, 200 meters away. From the home point I flew straight to the starting point. Then I pressed the RTH button on the remote controller.
Total time to get back: 100 seconds.
Starting point: 70 meters high, 200 meters away. From the home point I flew straight to the starting point, then I U-turned the spark 180°.
Total time to get back: 60 seconds.

Total time to get back: 100 seconds.
5s for a 180° U turn
30s to reach the coordinates right above the home point (while keeping the same altitude, ie 70m)
14s (!) for another 180° U turn
51s to land
