Sorry for the late answer.

This tool will continually alter the wallet settings too consider rising or falling dificulty and optimize the inputs in your wallet so that you stake more often.
The tool has an "learning" phase where it needs to adapt to your inputs and wallet settings (roughly a week).

I use the tool myself on a daylie basis and I do belive it rises my stake rewards at least for 50%. This is of course only a subjective number since I do not have any numbers to prove that.
