Our analysis\u00a0reveal\u00a0optimal pulse parameters, demonstrating that proper pulse design is crucial for achieving optimal performance, especially when using entangled states. We identify that moderate squeezing levels, in the low dB range, are most effective for realistic Gaussian pulses\u00a0and quantify the metrological gain.
