No, it shouldn't start at 0% and shouldn't go to 100%. If I did that then a 4% drop wouldn't register at all. I know Y-axis scams all too well and this isn't on

No, it shouldn't start at 0% and shouldn't go to 100%. If I did that then a 4% drop wouldn't register at all. I know Y-axis scams all too well and this isn't one of them.
