Feelings? Really?
You can't make 99.99% believe this,
1. Trying to determine force with the human nervous system is the most unreliable things you can do.
Humans simply aren't wired to determine force accurately.
Prove it to yourself, put exactly 5 or 10 pounds of pressure on a scale, blindfolded...
See how close you get.
2. Hold exactly 5 or 10 pounds of pressure on a scale for 30 seconds and see how good you are...
That scale is going to jump up & down like a little girl that gets a kitten, you have no chance!
The biggie of 'Feel' is ergonomics.
Again, 99.99% won't have a bench at the optimum height, or have a chair/stool at the right height.
I'm 'Disabled', I have a shoulder, neck & back that's screwed up...
I took the class on ergonomics & kinesiology, and went home to rebuild my workbenches.
I got a solid, comfortable chair with back & thigh support (no wobbles or leaning!),
And I put the presses in a position where I could pull/push the handles within comfortable range of motion,
Then built a bench design that didn't wobble, and adjusted the top height so the handle was in the normal, comfortable range of motion.
Shoulder, neck & back problems went away, AND the machine *Seemed* to run smoother, much less effort required...
And I was back doing one of my favorite things without pain & suffering.

As for mechanical movement, there is a reason humans invented all sorts of measuring devices,
Because we suck at determining small movements.
It's a predator/pray thing...
