if you have a 15v point with good data might as well use it

as you said it doesn't really matter, you might dip down below 10 at wot with a weak battery but not going to be significant in the grand scheme

So can I change the values in the voltage column or is there another function that scales that column?

no u can do it all there

just make sure the top is max and the bottom is min
