There are reported cases that for mixed evaluations, some of the raw scores in exported CSV don't match with the sum of individual scores.
Found inconsistencies in the db data. For each reported case:
the score field (which is the total score of the evaluatee) in evaluation_mixevals is incorrect
some corresponding records in evaluation_mixeval_details table have old modified timestamp, which shouldn't happen as all questions should be updated when the user saves an evaluation.
In each case, the evaluator probably saved the evaluation multiple times. And somehow for the latest save, some questions were not processed and caused the total score calculated incorrectly.
Can't simulate the case yet. But suspecting it is related to Javascript processing.
One possible cause of the problem is that somehow (network timeout during page load? or user submitted the form before onClick events fired?) some of the selected_lom variables are not set probably during form submit. Hence causing the total score calculated incorrectly.

In the UI, there is logic to set a
selected_lomvariable for each question when an answer is selected: https://github.com/ubc/iPeer/blob/ed1d8535518eeef5d24402b7a56c0c4d6807cd68/app/views/elements/mixevals/view_mixeval_details.ctp#L64-L67Looking at the logic for saving evaluation details, it skips processing silently if the
selected_lomvariable is not set for that question: https://github.com/ubc/iPeer/blob/ed1d8535518eeef5d24402b7a56c0c4d6807cd68/app/controllers/components/evaluation.php#L1083-L1085One possible cause of the problem is that somehow (network timeout during page load? or user submitted the form before
