If you start Terrain Protocol in Remote mode, it will run for 11 days or more (the preset repeats itself after 11 days). You don't need to split it by yourself. If it's in Contact mode, run each preset once in a day. It doesn't need to be 24 hours totally. You could see the guide in the software. Click >Detox>Guide Terrain Protocol in the Preset tab.
