All righty going to add something, so please don't everyone jump me at once.
I don't have the strongest ship but from Last years Qpedd I added 2 QPedd Assembly Line 3.0 to my ship. Since then I have only had 2 Crit return hacks. And better yet my little rank 891 ship, a lot of 1500 ranks and higher have trouble hacking me. In fact I blue badged a BT friend and he tried to hack me with no success, and laughed about it. Scientist do count as crew and they all help with Hacking.
