How does NovenAI standardise and interpret SkillSelect EOI data?

NovenAI standardises the official data by occupation, visa subclass, status, score band, state and snapshot month. This report covers 7 available snapshots and 12 subclass 189 score bands with data. When the official source suppresses a cell below 20, NovenAI uses 10 as the analytical estimate, so the results are not exact application-by-application counts.
