Even if mathematically possible, it's not in practice, if you look at the top #
1000 scores, the cheater scores really stand out (first 2 + those 3), because
all other players score 30 perfect zones or more, and none of them has a ratio
zones/perfect greater than 2.5 about. (while here we got 6, 17, 37).

So trust me it's a cheat for sure, also remember that this score is their
personal best, they would have scores much higher with less zones and more
perfect ones, which is a lot easier to accomplish.

You need amazing skills to reach zone 75, those skills would certainly enable
you to score at least 30 perfect zones, easily.
