Unfortunately: "Magic black box" as far as I know, what ever SRS wants and I haven't seen it explained yet how these ratings are actually made up. The higher your rating the less points you get and maximum is said to be 1000. I don't know of it tapers off gradually or each 100 points it changes the raise step. Rating gained in different games, no idea why it does what you described, odd indeed from seeing the results. On top of that the scoring for championships needs to reflect performances instead of smarting it out by playing in slots/sessions that are almost empty with no competition and getting full points for nothing.
