Absolutely. At one time in my life I spent many hours every week decoding MS1553 traffic. basically, 4 digit hex numbers. after about 6 months i was able to subtract in hex. and add. in my head. without writing anything down. some parameters where in 'BAMS' (look it up, it is cool). could look at 2 4 digit hex numbers and understand the magnitude of the angle differences without thinking about it. today, i need a calculator for anything...
