Whats the literal value "5" in the FastCapacitiveSensor.cpp#L32 about?

See https://github.com/Nyanyan/FastCapacitiveSensor/blob/master/FastCapacitiveSensor.cpp#L32

Is this refering to https://github.com/Nyanyan/FastCapacitiveSensor/blob/master/README.md?plain=1#L31

If so shouldn't it be simply: double INPUTTHRESHOLD = 1024 * 0.9;

With that there would be no need for the voltage parameter.

Just FYI, I've turned everything quite a bit upside-down: https://github.com/ensonic/FastCapacitiveSensor

I think the code is simpler. In any case, thanks a lot for coming up with the method.
