I have added a crude heuristic argument that the number of labels Whitehill was able to expose per submission (6) may in fact be what one would expect: <a href="https://github.com/WinVector/Examples/blob/main/puzzles/DataLeak/data_leak_size.ipynb">https://github.com/WinVector/Examples/blob/main/puzzles/Data...</a> . I think it is a fun argument.
