I want to give some updates, there was an earlier version of the Refracted Boulevard shortcut that was just less precise, and another trick in that track is slowing down when doing the shortcut in the first lap, so you can get an 8th place item (hopefully Bullet Bill) before the game puts you first.

I did mention the Bullet Bill strat and if the old Refracted Boulevard strategy is better then i could add it but i believe the new one is faster so i don't see a reason to mention it.

Lessnessv, I just watched your IL run of Refracted Boulevard, and if you think it is a good idea, in the guide under 'Individual Levels' i could reference that run for the shortcut when using a lower CC kart, because in a lower CC kart I am not sure if you can do the other shortcut.
