While 2 values per storage element is optimal for the sensor, it is the worst case for "data per storage element". The quantity optimized was "cost to store data". The three parameters are sensor characteristics, storage element characteristics, and the amount of data per storage element. Increasing the last makes the other two worse, but that doesn't tell us that minimizing the last is the optimum solution. Yes, ECC across multiple storage elements changes things.
