As you can see I got a total of 1116 Reward Points from Star Planet on December 23.
This is all on the same character. (I have heard that if you have characters on several worlds you can get 1000 points a day on each. But that is not the case here).
On other days when I visited Star Planet multiple times, the last session stopped accumulating points at the right point. I don't know what was different on that date.
