It was CatBus who provided this information thankfully. So all credit should go to him. I didn't know about this, but was struggling with getting the correct AR.

This will get you the AR that the people who made the GOUT (or more accurately, the Definitive Collection Laserdisc) intended for that video release to have. What relation that has to the actual film's AR is a matter of debate.

If you're aiming for "just the GOUT without extra fix-ups" then what you've done is right. If you're actually aiming for correct, I think you should refer to another reference, although I'd try to use footage from -1, rather than the Blu-rays for that AR reference.
