Tharrtell, you said exactly what I would have said only much more succinctly

The concept of needing rest so the body can recover applies to every sport or activity, especially those involving competition, whether it's figure skating or chess.
Yes, a woman can be 10% body fat, although even the leanest female athletes tend to be in the 11-13% range. However you do find women athletes way out on the fourth and fifth standard deviation who are 2-3% body fat. When I was getting my master's, the Univeristy of Utah NCAA women's gymnastics team was a dynasty. The team's top gymnast measured less than 2% body fat. When it's that low, genetics is the main factor.
Getting weighed underwater is generally the most accurate way to assess percent body fat, but the administrators of the test have to know what they're doing. Ideally you should be weighed three times and take the average of the two scores with the least variability, but those traveling body fat shows won't do that. Yeah, doing one of those traveling deals would be of interest. I don't know what your schedule is like, but if you're really interested in getting some measurements, contact some of the colleges and universities in the area and see if they have an exercise physiology program, especially a graduate program, and see if they need volunteers for studies. They usually use students but if you tell them you're a triathlete, they might be interested. Probably best to contact a professor working in an area you're interested in rather than a secretary. You never know. Finally, measuring percent body fat is still an estimation at best. The equations used were developed on average caucasion males and females and the biggest variable is bone density. Especially in certain African American male athletes, like pro football players, you can get a negative percent body fat, which of course is impossible. That's because bone density in African Americans tends to be greater anyway and in AAs who compete professionally in high impact sports that also involve a lot of weight training, their bones are super dense, which makes the equations inaccurate. Percent body fat is best used to see trends in an athlete's body composition, that is, to see if the diet and training methods are maintaining or lowering the percent body fat over time. A one-time test can be off by as much as 5-7% either way, depending on the test used and the skill of the testers.
Mathman, yes we do need body fat. Without a certain amount of body fat we cannot synthesize certain hormones and vitamins necessary for life and reproductive health, plus certain tissues need fat, like nerve tissue. It is especially detrimental to women to have too little body fat, but it is not good for men either. Before food was overly abundant for most people in countries like the US, obviously we needed fat stores to survive times of famine. But just physiologically and metabolically, humans need body fat. Most of us just don't need so much of it
