I find out that only SOME of the TPS wus do double checking, but not all.
Why?
Does that mean one of the returned result determine the number is a prime?

Doublechecking is done for random results to prevent cheating, but not spend as much results verifying as first-pass checking; also, all results that are suspected of being a prime (for example, the first returned result tells us it's prime) are doublechecked.
