I have read Deakin's articles too, and while technically one cannot disagree with him on this one, I personally don't do it, because it tends to follow that on the long trips on which I need to be precise with fuel I tend to be crossing barren terrain (or better still mountains
) and you don't want to tempt fate over that.
But if one is flying the standard type of "useless fuel gauge" GA aircraft (most of GA basically) with no fuel totaliser installed, then there is a much better case for doing this.
