Point remains a search is still a good start. That being said looking back at that chart it appears whacked.
Here's another from further down the same google list with a more fun title, http://www.sexyshoesiren.com/sizechart.html
I think his point is he doesn't know what 285 means but among the sizes in the chart I'm guessing he knows one that means something to him like the american sizing he asked about. I guess if his goal is actually to make it as complicated as possible he's certainly come to the right place.
And yes I agree none of it really matters as shell sizing is the only true way to size boots.
