Does "perfect alignment of cart" eliminate 100% ?

Does perfect alignment or close to perfect eliminate 100% inner groove distortion ?
I have alignmed my arm and table a lot of times only to still hear some IGD ? granting one can perfectly align the cart, can one eliminate it 100% on all LPs ? or does most of us here still get IGD ? only some are minimal ?

What cartridge are you using? My understanding is some carts are going to give a little more IGD than others, even if they excel in other areas.

I'm using an AT440MLa on a Technics 1200. Not the highest-fi setup, but the AT tracks well, and I don't hear any IGD.

And for the record, I set it up with the TT Basics mirror protractor(with a string taped to the sight line to help make sure it was pointed at the pivot).
