A higher sample rate alone
will not change the probability of overloading the ADC.
The percentage of meaningless samples will stay the same,
and consequences of overloading will not change.

A higher sample rate will help only if:
  a) it results in a higher equivalent bit resolution, and
  b) the input full-scale range is increased so to keep the equivalent LSB value at the previous level.
