When R3 and R5 reset this week, I will open a new world (same concept as Rδ) that will alternate with Rδ (currently halfway through). To keep the two Rδ worlds equally spaced in terms of resets, the speed for both will remain at 20 minutes per day.
Currently the plan is to have the new world as 1970-2010 and change the existing Rδ to 1990-2030 after this round is finished. Does anyone have a strong objection to this arrangement?
