I think you are missing the point. The fact is Athletic Run works in addition to the other travel powers such as superspeed or super jump. Both those travel powers get additional speed or jump, where infiltration gets nothing. This is making it a weaker travel power because of this. That is why I said it should get 50% of what athletic run gets to both speed and jump. With one slot in infiltration it is less than getting a 50% bonus would be from athletic run.
