I am not and expert in this area but 10% on person A and 10% on person B does not look the same. I wish it did but it just is not the case. Some time ago, I spent time in a human performance lab where they used 3 different BF% testing methods including hydrostatic weighing. I was amazed at how different people looked even with close BF%s.
In the end, BF% is nothing more than a %. Aim for the being happy with yourself.
