Re: piston rings?
For reference for the OP, I found "standard" tension rings to be in the 18-24lb range.
I've also used the fish scale gauge to check the drag of the oil ring using the "dynamic" method. Like most gauges, weather stations, etc., the calibration will vary, plus other factors. So I use the same one for my comparisons. "Your results may vary."
