It is currently hard for a pirate to get between Kretogg and the Qorel expanse. This helps to bypass the worst two systems, with significant Za'lek, Dvaered, and Empire presence
The existing hidden jumps provide no shortcut; they are the same number of jumps as going through normal jumps. It seems they could serve as a way to bypass Dvaered space, and these extra jumps help with that. It is still necessary to pass through one Dvaered system (Amaroq) and the systems all have a Dvaered presence, but this makes it at least a bit more realistic for an enemy of the Dvaered, knowing these jumps, to get between Za'lek and Sirius space.

It might make sense to do this in other areas, since radians are often easier to work with when dealing with functions like atan2().
