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.
Dude he said somewhere in this thread that this time we can earn more points than required to unlock every checkpoint.
