 The context of our work is the Dodona learning environment, developed at Ghent University\nbsp{}[cite:@vanpetegemDodonaLearnCode2023].
 Dodona gives automated feedback on each submitted solution to programming exercises, but also has a module that allows teachers to give manual feedback on student submissions and assign scores.
 The process of giving manual feedback on a submission to a programming exercise in Dodona is very similar to a code review, where errors or suggestions for improvements are annotated on the relevant line(s)\nbsp{}(Figure\nbsp{}[[fig:feedbackintroductionreview]]).

 Weights are assigned using two criteria.
 The first criterion is the size of the pattern (i.e., the number of nodes in the pattern), since a pattern with twenty nodes is much more specific than a pattern with only one node.

 These evaluations were run on the same hardware as those for the machine annotations.
 For one prediction, the average time ranged from 0.1 milliseconds to 150 milliseconds and the maxima from 0.5 milliseconds to 2.8 seconds.
 The explanation for these wide ranges remains the same as for the Pylint predictions: it all depends on the number of patterns found.
