They can be a barometer, but don't take them as God's word. When you get below 20%, you're usually considered healthy.
Around 15% is where most people really start seeing definition. 12% is athlete. 8%-10% is Brad Pitt. 4%-6% gets below essential fat, isn't sustainable, and is usually the dudes on gear with nasty veins all over the place.
If you really want to push yourself, 12% will look damn good. Match the diet to boot, and you can float in that 8%-12% for as long as you keep at it.
Be patient. It takes time to achieve.
Also remember that, depending on your body type, muscle definition may come sooner or later in that fat drop. When dropping weight, the body also eats muscle. That's where safe supplements like whey and creatine offer great benefits.
You put it better than I did. Though, I would argue (not saying you believe in body types as you were just using the term to make a point-I'm just being pedantic) there isn't a true "body type" (the old Mesomorphs, Endomorphs and Ectomorphs thing). That was a bunch of BS. Again, ideal is determinant on you goals and usually that is either what you want others to see or how you want to look in the mirror.
I really don't do BF% tests. I do not trust them. Machine or caliber. Even Dexa I remember I used an Inbosy scanner at Craig Ranch as a trainer and it measured me consistently at 16%, though I was pretty damn lean. Than I went to another gym and used their Inbody Scanner and was 13%. Which was much more likely given how lean I was. My friend (also a trainer) laughed and said she thought THAT was too high. I tried to measure under the relative same conditions, meals eaten that day, time of day, etc. Point is, those things aren't very accurate all the time.
Right now, I am probably around 15-17 honestly. Maybe higher. Better not be lower as I am working on getting bigger. I will do a mini cut here in a few months. Probably 8 week slow one. I am 6'2" 205. I do not want to lose too much too fast but probably can get down to 195-190. I still have a good hint of abs. Hell, I still look lean for this size. I've been as high as 220 (really hard to maintain that) and as low as 165 (too damn lean!).This is the biggest I feel like I have looked in terms of muscularity. I might have been a little "bigger" in 21 at 220 big actually feel like I'm more muscular and a lot leaner. I lose weight fast and a lot of that is genes and how fit I am and have been since 9th grade. But I get it's hard for others. We all have our struggles, no doubt.
