We'll still stick with jump_beef, and I'll tell you why. Our academy is dedicated to beginners, people who don't have a single experience in jumping. By introducing a map that they may know (players or stream watchers), they don't feel watching only pro players racing in 2 minutes a map they tried during 4 hours.
Usually when people want to watch jumping they like to watch people better than them. Watching somemone of the same level as you or worse is much less entertaining, because you know that you could easily do what they're doing. When you watch a "pro jumper" you get to something you didnt think possible, and for me it gave me a goal to become better. Watching newbies take 10 minutes to complete beef doesn't sound very interesting. Anybody who feels bad because someone beat their time shouldn't be speedrunning anyway.
