X is not irrelevant if that's what you believe the argument is for tuning to vswr dip. Every decently installed antenna I have ever analyzed showed the X curve highly correlated to vswr curve. If they are showing 2 completely different stories, you should suspect a problem.

Given that they both correlate, I'm then going to ignore X if read through a feed line because I know that vswr proves resonance, while X is certain to be skewed by feedline reactance.
