I play a similar modified format. MR break rules on a 4" cornered Rasson table.
Take ball in hand and run out, it's one point, If I miss it is two points to the ghost.
No ball in hand and break and run, it's two points to me, one point to the ghost if I miss.
If I choose to lay a safety after the break - the point is up for debate. If I lay it successfully, I let myself take ball in hand after, if I run out I get a point. If I miss ghost gets a point. If the safety is poor, the ghost gets a point.
Usually racing to 5 or 7 when I have nothing better to do.
