Sorry guys about making you share a nomination but they are awfully short posts.
In addition, half the nomination if to contrast your responses with the others which, IMNSHO, are too quick on the draw and don't get to the real point.
Message 6Here Crash points out the deep, underlying error in the calculations. he does it succinctly.
Message 7Here FallacyCop points out another deep flaw in understanding (this one I missed on my reading of the OP).
There is often no need to go on at length if one thinks over the issue and looks at what is really going on.
These are examples of posts that we should have more of.
However, that is not to denigrate RAZD's excellently laid out (if lengthy because they need to be) posts which I have nominated before and feel need another highlighting again.
There 3 for the price of one. Thanks guys.
