Overshooting means that you increase the tension in the first segment of the string (the segment leaving the tuning pin) to the first friction point before the speaking length moves. If you have a piano with a rendering problem and the friction points don’t release quickly, then you can easily increase the tension in that first short segment past the break point and the string will break. If you tune with counter pressure applied to the tuning lever that compensates for the twisting of the pin, you can move the pin in the block without increasing the tension in that first section, no overshoot. The risk of exceeding the break point then is minimized.
