Percent of comments in your code?
How much commenting do you do?
For instance, I have a project I'm working on in VB right now that is about 4500 lines and when I look at the stats, it says 25% of that is commenting. Now granted, I don't comment too much inside my code, but I do like to throw in good explanations of what a function/procedure is for and what certain random numbers mean (other than constants).
Another thing that bumps up this number is an addon in the VB IDE that throws in 6 (name of creator, time/date of creation, name of procedure, and description + 2 seperator lines) lines minimum of comment block for each procedure that I decide to do error trapping on (most of them).
I guess I'm just wondering what kind of percentages you guys have.
