I usually replicate someone's results for one of the two reasons: 1. I don't trust the results 2. I want to understand their work in sufficient detail Usually these reasons apply when I'm building directly on top of someone's work. This is not always the case. Often my research is based on ideas which could be tested by generating my own results. As long as I can replicate my own results I don't see a problem.
