Are there any reasons that we would not benefit by requiring that recommendations for exclusion on the grounds that a project is too hard or too easy be accompanied by specific reasons for saying so, supported by actual empirical evidence instead of just mentors' opinions?
I would also like to encourage mentors to express both a textual opinion along with a numeric score on as many proposals as possible. Can we agree on a minimum acceptable proportion? I personally will try for all of them, and I'm sure I'll be able to cover 75%.
