How do you have the 2.4955V in memory? Is that a word? Because that wouldn’t give you much range past 6 Volts.

You can keep the resolution and take the mean of the last n readings if you can calculate it, which you probably can.
The larger n is, the less responsive your potentiometer is, at least “apparently”,
but the smaller the fluctuation you see, the easier it is to pad out.

If you’re going to blow out a variable used to calculate the mean, you can add and divide small groups of variables
to arrive at a new smaller group of variables, and work down to one number that way.

Heart rate monitors at least used to do this because the interface to the body, and radio between the chest sensor and device was so clumsy.
