One of the reasons I love sight glasses is the fact that you can watch goings on,your downcomers will give you critical feed back as to how much reflux is happening,with 4 or less plates for rum or whiskey the amount of take off would be equal to or a little less than what was flowing from your downcomers to the boiler,with a neutral run your take off would be less than a 20% of what was flowing from the downcomers .In short 4 or less plates 40-50% collection to 50-60% reflux,neutral 10-20% collected to 80-90%refluxed,as a rough guide.So watch those downcomers for blow thru as well wich will cause a plate to flood as the reflux cannot go down the downcomer with vapour running up it.cheers hillzabilly ;-)
