How many points do you get after beating the bosses on the 21st and 49th for each one? single, double, and multi.
It actually increases as you go up. The first is 5. Then 6. Then 7, 8, 9, then 10. The boss will give you 30. Every set after that will give 10.

Super trains give you 5 BP for every set you beat, and 20/30 BP if you beat the leader. Hope this helps...
