I wish I could help. Here is my two cents if it helps you realize you are not crazy. As a college professor I try to align points with two factors in mind, amount of effort and relevance as a measure of subject matter understanding. In general, I try to correlate amount of effort and relevance. I also make those assignments more "points" so that simple mistakes that require some type of deduction don't end up dropping someone an entire letter grade (ie. from a 10 to a 9) just because it's not perfect.
