I want to speedrun this game on my PS4, but i don't understand what R+ and then a number means. Please help.

Hi! I want to speedrun Mario Galaxy 2 Any%, but i don't want to record the gameplay. I'm also new to speedrunning so some help would be very nice. I also don't know how to submit speedrun gameplay from a Wii, so please lend me a hand. I just want to try speedrunning for fun, but i'm serious about doing it. Thanks!!!
