It is probably more accurate to consider the DR of the negative. On my condenser enlarger and with grade 2 paper, I need a negative density range of 1.25. For grade 3 paper, I need a dr of 1.0. I believe an "underdeveloped" negative will have less grain and in some ways, better resolution. However, a more fully developed negative will have greater tonal separation and greater accutance. Greater development would be necessary with diffusion head enlargers and preferred for larger formats that can take the hit on resolution and grain. Since I have not fully developed my skills with cute little film, I take advantage of longer development benefits in tonality and accutance. If I had to use 35mm, which can happen, I would likely make a flatter neg and use harder paper. I have nothing against VC paper, I have some for negatives that are outside the range of Grade 2 or 3, which I have. I am at a point though, where everything is usually perfect on grade 2. A densitometer and a step wedge will go a long way in perfecting your process.
