What's "slow"?

As a distance open water person, I'm always amazed at how fast short distance swimmers actually swim (those of you out there who are shooting for sub-one minute 100's know who you are!!!) I definitely do some sprint work in my training, but I'm still impressed at the times people put up who are real sprinters. So I'm curious - what do people consider a "slow" 100? (Assuming that one is actually swimming instead of noodling.....) :snore: .
