Rules and numbers are not mind-independent regardless of whether we assume that an omnimax god designed them to exist. I have no idea why you would assume that to be a relevant factor.
That's like saying the mechanics of a video game are "not mind independent".
The God is not your mind. It exists regardless of whether or not there are humans to perceive it. What it creates exists whether or not you are there to perceive it.
That is mind-independent.
That's not always the case. Senna secured the championship by crashing into Prost's car in the F1 1990 season, for example.
Senna winning the race would have scored more points and also won the championship. Senna would have 1 more race win in his career stats and would thus have been more successful.
That would be better performance.
