Sperzel locking tuners string breakage at the peg

I broke 2 strings before it hit me: you're not supposed to loosen the string completely after having tuned up with Sperzel locking tuners.
The thing with that is the string makes a really tight turn at the peg when tuned up and when loosening again it bends back, weakening that spot.
Rinse and repeat for every tune/detune cycle eventually breaking the string at the point it makes a turn to fit into the peg's opening.
Better would be, if you're planning to ever loosen the string that is, to insert it at a 1/2 or even 3/4 turn around the peg so that the weak spot never bends back when detuning.
Update: come to think of it, even 1/4 of a turn around would be enough. As long as the bend at the peg doesn't get straight again it should be fine.
