There is a workaround for HUP, but the science hasnt caught up yet.
I think, and Ive been thinking this for some time now, that if you can measure the tiny fluctuations around the particle's field, you can know its relative momentum, and as for position you can deduce those statistically later on, thus giving you a relative equation
Saying uncertainty is independent of method is ignorance. HUP is _exactly_ based on measurement flaws. It pertains to both position and energy measurements, and so far this unfortunate flaw in measurement has been delaying a lot of scientific progress
