I wouldn't get sucked into that discussion Jon.
I regret that data collection and graphs have largely replaced higher thinking in our dumbed down society since it's actually meaningless . You can gather and present data to back up anything you want to prove - I was doing that myself forty or fifty years ago with figures for press and public consumption. Also , you can and will be misled even if you genuinely draw conclusions from figures alone.
I know you won't accept that, but on the other hand, it's no use trying to convince me that such simple arithmetical sophistry is credible.
It's a pity that so many people are happy to sub contract thinking to "experts" because they're no more trustworthy than anyone else.
