A DCO (Diff. chart obby) is a Roblox obby trend where every few stages of an obby gets increasingly harder with a chart showing each difficulty. It probably started because of Tower of Difficulty Chart in JToH, since they usually always have the jtoh difficulties then some JHT (JToH's hardest towers wiki) difficulties after.
The one I made is a jump per difficulty, where each stage has one jump (well besides last one lol). Good luck!
