the power of two rule applies here, I assume
If you oversampled by something that isn't so conveniently neat and tidy like 96/44.1 then you can't eliminate all but every x*n sample where n is some power of two (or some other integer that is not a power of two!) and retain the information.
If you had an algorithm which could reconstruct the last ten seconds of a twenty-second recording based on the first ten, you could use it to predict the future. With such an algorithm you could figure out what number would be called at the roulette wheel in time to place an absolutely sure bet.
