You do not get a faster drive right away. By studying it it would be faster. On the hyper gate core. The malevolent benifit doesn't make as much sense as it being the pragmatic bonus. If you study it before you use it then you will be able to use it better. The faster hyper gate core should be pragmatic not malevolent, because studying it would let you use it better, not by implementing it right away. This is the same issue as before you shouldn't get better bonuses just because you are evil.
