non-repeatable values from QSlider

[Phillip-M-Feldman]

I'm using PyQt5 version 5.9.7. I've created a QSlider with minimum of 0 and maximum of 100. When I drag the slider all the way to the left, I get non-repeatable values--typically 1 or 2, and occasionally an actual zero. This is problematic when one needs an accurate value.
