Narrative:

While approaching [the] gate to park in pvg in the rain; the first officer mentioned that he has seen aircraft overshoot the stop line on more than one occasion. He asked me to approach the stop slowly and stop immediately. I approached the stop line cautiously; as I usually do; and stopped more abruptly than usual. After stopping; the [parking guidance system] said 'ok'. In spite of this; ramp personnel got on the headset and told us we would have to wait for a tug to push us back 3 ft because we were past the stop line. I do not know if the wet ramp can cause [parking guidance system] issues; but if the wet ramp is not an issue; we need to have the pvg [parking guidance system] calibrated. This overrun takes quite a bit of time to correct; costs the company money; and is a headache for passengers.
