4x4 3x3 2x2 & 1
You have 30 minutes working time to fly 10 times only. You must try to fly 4 times 4 minutes in a row, then 3 times 3 minutes, 2 times 2 minutes and finally 1 minute. These are maximum flight times.
Maximum score would be 30 minutes total time minus a second for every flight, being 1800-10 = 1790 seconds.
Try to make a 4 minute flight, you do not have to make the 4 minutes but the time you fly short will be lost in the total score. Next try a 4 minute flight again, and so on until you flew the 10 target times. There is no slack, so it is a turnaround task. But if you landed early for more then 10 seconds, take it easy with your turnarounds!
Flight 1: 240 seconds
Flight 2: 245 seconds
Flight 3: 220 seconds (you've lost time on this flight, but gained some slack for turnaround. Take it easy from here)
Flight 4: 202 seconds (not that easy, come on!)
Flight 5: 178 seconds
Flight 6: 184 seconds
Flight 7: 160 seconds
Flight 8: 123 seconds
Flight 9: 118 seconds
Flight 10: 21 seconds
The total for this task = 240 + 240 + 220 + 202 + 178 + 180 + 160 + 120 + 118 + 21 = 1679 seconds.
The best time gets 1000 points
Theoretically it is possible to fly 1790 seconds
If someone did make 1790 seconds (1000 points) and you did 1679, then your score is (1679/1790)*1000 = 937 points
