Just some suggestions
For rank 100k - 200k, you should choose near 3 to 3.5 star maps (still quite hard but it'll be better), then advances to 3.5 - 4 in the near-end stages.
Plus there are 2 maps in the pool that are very short (In my room and Granat). Consider choosing longer ones (90 seconds or up would be nice).
Kudosu please
