Also prof: me too. I'm much more likely to provide comments on the first couple of exams I grade than on the later ones.

I've found that gradescope is helpful in this regard, because it at least forces every point assignment to be matched to a rubric item. I don't have data, but I believe it makes our grading a lot more uniform compared to the pre-gradescope days. (This might be easier in grading computer science exams than in more subjective areas, though.)
