Greeting, as you have found this post!

For those who wonder and wanted to calculate their said numbers when it comes for Levels will be listed down below.
Feel free to swipe the numbers in case of research purposes in the testing server. 
But do it on a 0 apt race without any exp boosts for the most accurate results

Expect this to slowly but surely update as I further cook with this.
