Replying to Binding toe mounted a little off

I gave my buddy a pair of my skis and some PX12s to throw on them so he could ride this season. He mounted them and rode them and gave them back recently because he got his own pair.
After looking at them, he mounted a toe piece a little off at an angle. There is about 3mm of change in the toe angle. Meaning, if I measure the sidewall to the tip or tail of the toe piece, there is a 3mm difference in the measurment from the right side to the left. How badly will this affect forward toe pressure and releasing?
I may take them to my shop to see if they can pass a torque test, but I am wondering if this is a waste of my time. I want to sell these skis, but dont want to if this will end up hurting somoone. I also dont want to remount them.
