Indeed. My favorite (which is, I suspect, where a lot of Big Numbers come from) is folks who have clearly extrapolated from a peak rate, like "We peaked at 20,000 transactions per minute over Black Friday, so we need to be able to support 10 billion per year". But if you dig a bit more, you find out that their normal rate is more like 20 per minute, and that guess what, when they hit that peak, everything in their infrastructure was queuing work. So no, they don't need 10B/year capability: they need three orders of magnitude less. Or maybe two, to be safe.
