I interpreted Tugly's meaning differently. I think he was trying to convey the idea of wanting the least amount of resistance in the ground path... meaning as few point to point connections in series between the battery and the block.
In other words, if given a choice between two ground circuits...
A. Cable from battery directly to block
or
B. Cable from battery to body, then another ("jumper") cable from body to block
... then the preferred embodiment of a ground circuit would be A, as it contains fewer "jumpers", or connections, or points of resistance, or points of contact failure.
What you are talking about is direct and separate grounds for each component in a given set of circuitry... which essentially is exactly what I interpret Tugly to be talking about. Essentially, your anecdote illustrates the same direct connection to ground circuitry that Tugly is trying to convey. You guys are on the same page, as I see it.
Thank you for the detailed clarification/confirmation. Sometimes I need big pictures that are drawn with Crayons....
