Nothing. 4 Mifune is the fastest, but Lin here is saying he wants the runs to be SLOWER.

Say Lin sets quest repeat to 100 times. Then, if he does the fastest possible runs, after he uses his full energy gauge, he won't be able to level up. This will cancel the Quest Repeat, or he has to use a gem to restore his energy. By making the runs longer, Lin's energy gauge has more time to fill up, and then he will have more energy to do more runs because more time has passed. This will let him do enough runs to level up, so he doesn't have to check back on his device and can do other things while letting Brave Frontier repeat the quest.
