Use this link after September 1st. This is the new one, unfortunately the projection section is still under construction.
I find that the Heat map is also AMAZING!
You’re only level 5, so you really only have three levels to worry about, because level 1 and 2 are “quick” levels. If you load the heat map and count the days to level 3 and to level 4, you will know around how long it takes you to level up on average. (Divide by 2 lol)
This is my guide of a simple schedule to consistently get seven day levels. You could easily make it 8 or 9 day levels. I think once you understand how levels work it will allow you to choose the length you want the levels to be instead of being at the mercy of some system.
