> and since there isn't a clear delineation between what is the "head" and what is the "body" At any appreciable scale you get a reduced flow/pause in output as the mixture finishes boiling off the methanol and has to increase in temp before boiling the ethanol. It's a 10+ degree temp change so it's not instant. You need to be creating a small batch on a heat source that's way overkill to not have a defined difference.
