FPC impedance design line width and line spacing parameter reference value

The simulation calculation of FPC impedance using POLAR SI9000 and KICAD is inaccurate. Jiali Chuang FPC Engineering measures impedance through actual board making, reversely infers line width and copper thickness. The parameters are as follows:
