YMMV but personally it makes everything 1-2 wipes to ‘verify’/dry. Got one in 2020 to lessen TP usage, which it does really well. I think you’re underestimating how strong the stream is (which is variable/controllable) and overestimating how ‘stuck on’ any residue is. Works kinda like a pressure washer where you can’t move/angle the washer (on the affordable ones) so you move the thing being washed for full ‘coverage’.

Regardless, if I got muck on my hands would rather rinse them in water than just wipe them off with a paper towel.
