Every year WiWi bloggs performs a ranking of how well they believe acts will perform. They do this in march before any pre-parties and do not change their rankings after. The rankings are out of 10 and generally an above 7 is viewed as very good. It is a good rough indicator of who will do well and the top 20 acts based on odds from April 28th 2018 are also featured below for comparison (from eurovisionworld).
