Do handlebar body composition scales reduce noise, or just add more numbers?

​

I have been using a basic smart scale for a while and the body fat / muscle numbers swing around so much that I mostly ignore them. Hydration, dinner timing, soreness, and even standing slightly differently seem to change the reading. I keep seeing multi-segment or handlebar-style BIA scales marketed as more complete because they measure through the upper and lower body. In theory that sounds better than a foot-only scale, but I am not sure whether it actually improves trend quality or just gives you more precise-looking noise.

For people who track this seriously, did moving from a regular smart scale to a handlebar body scan style device make the data more useful? Or do you still only trust long-term averages?
