Interesting info.

spoke today with the Coach of the Olympic Champion in the 100 meters for women, Jodie Henry of Australia. (Coach Shannon Rollason)
Prior to Athens, Jodie was working for 40,000 a week in 8-9 sessions a week.
today, she is at 30-35,000 a week, in 7-8 sessions.
In other words, basically 5,000 a practice, but many practices.

This is, i believe a workable formula for good sprint performance. NOT for middle-and-distance swimmers, but a good 5K a day beats lousy 10-14-18K a day at slow speeds.

To swim fast, you have to swim fast in practice! Enough said! JL
