Had my BF tested - water tank (managed to get it as part of my medical insurance health check)
10.8% - have visible abs (bit blurry definition in lower) . This seems to be my sweet spot in regards to performance (resistance/metabolic training + Muay Thai), as well as my ability to handle carbs as well as my general well-being/feeling good.
To augment CT point in regards to low carb diets - FOR ME 300g carbs a day, 160g protein and fats from fish oil/protein (3000cals total) works far better at this BF than the same amount of overall cals - Higher fat, lower carbs.
In my experience, when you get to a lower bf and maintain your set-point for 1-2 months, it's easier to maintain that bf + re-comp in the long run.
I've totally changed my opinion and stance on carbs...I rarely go below 150g, even on off days, and do 'diet' anymore - I eat and train for performance and adjust depending on my current goals.
Never felt and performed better and I'm 39 next month ;0)
