Update: Hi Score 22,816
I figured it out. The goal is to hit closer to the target (ofcourse). Doesn't have to do with either it's good or perfect. Closer means more points. So I focused in precise delivery -with an average mistake of just 19 km!! - and the result was 22,816 score.
Here's the video:
Also I have a couple of mistakes to mention.
1) I figured out that "Good" delivery gives more points than "Rerfect" delivery. For example, I've got 7629 pts with 13 perfect & 25 Good deliveries and 6350 pts with 23 perfect & 13 Good ones. I think that at least the same pts should be given for perfect and not less.
2) The corect name of the country you mention as "Macedonia" is "North Macedonia". There's been a dispute for many years between Greece and the Former Yugoslav Republic Of Macedonia (FYROM) and the two countries have come to an agreement in 2019 about that name. Prespa Agreement
Otherwise congrats on a very good idea, gives a true prespective of the globe, contrary to the maps we are used to.
PS: I love the shortcuts through the poles :)
