I think it is also possible to create a program that uses time very irregularly
(for instance if a move looks to be good immediately, take a risk that it is
obvious and make it) and occasionally make mistakes. Such a program would be
almost impossible to catch based on most detection methods (lack of blunders,
regular time use).
