I decided to do some math to see how long an All Map Packs speedrun would take optimally. • 65 map packs • 3 levels per map pack × 65 map packs = 195 levels Let's assume each level takes about 90 seconds, or the length of a normal RobTop level (a lot of these levels use a RobTop level song and are the same length as the song). • 195 levels × 90 seconds = 17,550 seconds • 17,550 seconds / 3,600 seconds per minute = 4.875 hours (4:52:30) At best, an All Map Packs speedrun would still take about 5 hours. If each level took 10 minutes on average, you're looking at a 32+ hour speedrun. Good luck if you want to try it :^)
