This was also echoed in the discussion about the last section of the test set. This section included a significantly higher amount of low-soluble compounds and therefore highly skewed the prediction of anyone using id information for their prediction, both those using it based on informed assumption, such as Dr. Rohde, and those using it by chance, such as the leaderboard first place. This was also supported by our analysis of Dr. Rohde's intuition that plate position did not significantly improve our results, whereas plate number did significantly improve results.
