Thanks for the graphical representation of the calculation.
As you said it becomes harder as your reputation grows.

As you can see, is it very easy to raise your reputation at the beginning, but the higher your reputation, the harder it is to increase it. In fact, each time you want to increase your reputation of 1 point, it is ten times harder!

I was wondering why my reputation has stuck at 48 for almost a week!
It is good you have given a great explanation here.
