I actually went to the webpages of all of the programs to which I applied and usually they're pretty explicit about what they do/n't want. It took me all of about an hour to make an Excel table. You're paying $30 a pop, so you might as well make it count.
Some places have different reqs just to see if a) you read the webpage and/or 2) to see if you're committed (um, Wichita). With the app:spot ratio of ~100:1 for most places, it wouldn't take much to turn away an applicant, so it might be in one's best interest to do what they ask for, no more, and no less.
If in doubt, email the program contact and make a friend.
