Resolves to the year when the 10th drop falls in the University of Queensland pitch drop experiment. Automatically resolves to "2031 or later" if the 10th drop hasn't fallen by 2031.

Resolves N/A if the experiment stops before the next drop falls, the answer is unclear, or the experiment is tampered with in a way that affects the time of the drop to a non-negligible degree.

Year start and end times are based on Queensland time.
