Math operations execution time

Isn't the 12-14-16 bit reading just a guess about being between the 2- 10 bit readings which could be off the expanded factor bits ??
If the a/d values do not bounce in the 64 samples, the actual voltage could be up or down on that step but the guess would be middle.

Yes, but in practice the numbers jump around enough so oversampling can extract more data from the result. The main drawback is speed, but it is very effective.
