Thanks Joe!
I'm really new to this stuff..

Im not sure i understand the scaling thing.
if 4X output higher resolution to 1.25, 1.50 VS 1, 2 of the 1x, where is the scaling?
Does it affect the DistancePerPulse calculation from our side? we devide the circumference by 360 or 1440?

What about measuring distance? should we use 4x decoding?
