From Toadwater Guide
There is a lot of math in Toadwater, and some of it is very complicated.
The logarithmic scale for calculating your skill level based on your total experience is one of the most complicated formulas in Toadwater. It is given below:
log10(XP)3 + age - deaths + 1
Where XP is in points, age is in integer years (truncated), and deaths is an integer.
