Does "perfect alignment of cart" eliminate 100% ?

You can download a Stevenson protractor at the link below. Actually, it combines Baerwald and Lofgren (presumably "B"), too. I've never had any problem printing the protractor at 1:1 onto an inexpensive photo paper. Works fine for me. The only possible caveat is that you have to line it up to the exact pivot point of your tonearm, which I understand is difficult with some arms. Go the the link below and click on the KWillis Universal Accutrak Protractor Version 2.

Does a 12" inch help reduce the IGD ?

In short, is it a majority of us experiencing IGD or some of you guys can claim that you can play most of your LPs w/out any IGD ?

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).

Nolitan,

yes, I can play my LP's with no inner groove distortion. I would wager that most everyone I know whose systems I have heard can also play with no inner groove distortion. If you are hearing this there is something not correct in your setup.
