To quote myself again, since our friend Lian seems to be fired due to the lack of information he provides.
Levels 7 and 9 do not have an increment of 10 points. My progress is at level 10 now, so I don't have info on higher levels yet.
This leaves the required number of points at 1350 - 90 - 70 = 1190 maximum. So the 1230 points for all challenges are (for now barely) sufficient.
Please don’t call me names.
And read back this thread, if you are really interested. He said that not all levels would have an increment of 10 points. I asked him to clarify which levels. After that, there was nothing but silence of our friend Lian in this thread. I saw that he was active somewhere else on this forum. I’m really glad that he is still alive.
I decided to keep sharing the information I gathered myself, since it might be useful for others as well. You are very welcome.
