Huh, I thought if you held the outlet of the still at 79c until you stopped getting distillate then you could be reasonably sure that you took out most of the the majority of the methanol.

It’s more prevalent, and you might reduce the ratio of it, I was just pointing out that more than you expect will remain in even after tossing the fores.

And even if you just distilled until it was basically water coming out, then re-blended everything, you have not significantly worsened the ratio of the two

You can. I think parent is using some technicality of how distillation is not going to get you to 100.0000% purity.
