A Weird Dilemma

Hello. I wonder why are the values related to a detuned harmonic filter reactor in terms of kvar so close to capacitor banks' while the value given as p:5,67 , 7, 14 etc means that in a filter design, those reactors impedance and capacitor banks ratio is as low as these numbers. Since the reactor and capacitor is in series, power is proportional to impedances (At most a ratio of 1,73 comes from delta branch of the bank) so why do we oversize these reactors while designing!
