Should I add short level sections? Or only any% should be the only FG category

We are good as it is right now! also i wanted to add here... I play on computer and my monitor was on 120 HZ (refresh rate) and my IGT was running to quickly, level 6 was impossible. So i downgraded to 60hz (in "Display" on windows10) and my timer gave me more time to finish the level... i didnt get an advantage for my time, i simply could finally do my lvl6 like the others, its only the timer that was running too quickly , not the whole game
