I have a calculator that is correct 80% of the time. But don't worry, every time I use it, I check the results myself.
@MartinEscardo my reports are correct 85% of the time but that's ok, my boss is happy to double check them before sending them to our customers!
@ehproque @MartinEscardo Even 95% if you burn the whole planet and then fill the orbit with data-center satellites
