I really can't add a lot more to the analysis posted Labroides, which sums it up nicely.
As a back-of-the-envelope calculation, the recorded flight path represents about one third of the battery duration between 93% take-off voltage and critical landing at 10%. Seeing that most of your flight was at idle and just being blown at the mercy of the wind, it would be reasonable to assume it would continue to discharge at a similar rate. Assuming it continued on a heading of approximately 246°, it likely travelled 3 times the recorded 1300m before commencing autolanding at 10%, somewhere SW of Quarmby. From that altitude (400ft) it would take about 2 min to land, all the time being influenced by the wind, taking it another 400m or so and landing in NW Longwood. Now draw a really big circle around that point and that would be your initial search location.
This looks like a case of not having a plan to deal with how to tackle high winds when the aircraft is being blown away. Not sure why you didn't just land or at the very least descend close to the ground (where the wind would be weaker) instead of drifting towards hospitals and beyond.
