While an interesting question, in my opinion doing sets of 100 freestyles on a tight interval has limited carryover into the actual swimming of a 100 freestyle.
The best I ever managed was sets of 100's on the 1:20, and frankly I'm not even sure I could make five. But at the time I did the 100 yards in 51.9. I have a good friend who could hold 100's around the 1:00 interval, and he did a 50+. So there was an enormous workout difference, but less of a race difference. (Granted this fellow could do a 100 breaststroke in about a 1:01, which is way faster than I.)
