Three shooters have different eye-sight:

one on the minus-side

one 20/20 vision

one on the plus-side

All three adjust the ocular for optimum reticle sharpness and use the same scope, under the same conditions - and they all end up with different numbers on the parallax-knob.

Is there a connection between ocular setting and percieved freedom of parallax? I have been taught that the ocular adjust focus on the reticle / parallax adjusts "target to reticle" but on the other hand I have experienced the same as above when borrowed friends rifles/scopes as there has been a difference in parallax settings between friends and me. (usually I don´t bother what the parallax-knob indicates.....)

The ocular adjustment is the difference. This is especially true in first focal pane scopes. If the reticle doesn't start clear at the same place, it defintely can not end up at the same place on the focus knob.

Remember the focus knob brings the reticle and the target into a parallax free if both are set to an individuals eye. If using the same scope for multiple shooters, eye placement becomes MUCH more critical.

That's where I'm a bit confused....please bear with me.

By moving a lens (behind the reticle) at the ocular the reticle becomes sharp.

By moving a lens forward of the reticle the parallax is adjusted.

In my world the reticle never moves, thus focussing the ocular wouldn't affect the parallax at all. (but I'm experiencing some sort of interaction between the two)
