I was watching some old videos and found this amusing.

Now that's what I am talking about! That's real figure skating! None of this feeding hundredths of a point into a computer.

for a math guy, you are easily disturbed with basic cop arithmetic

So true, and there is a mathematical reason. To do the CoP the only mathematical skill required is the ability to add.

Ordinal judging, though -- that leads to the huge and fascinating field of "Social Choice Theory," with applications in economics. political science, and many others. The key question is, how can society as a whole (in this case the "society" is the panel of judges) come to an optimal decision based on conflicting views of its individual members.

Indeed, economist Kenneth Arrow won a Nobel Prize for proving mathematical results showing that no system is perfect. (I could have told him that and won the Nobel prize for myself. :yes: )

well not quite, there are deductions as well as factors in COP

ordinal ranking can be done in so many ways... i heard of a story where a teacher would throw essays randomly in the staircase and would then ranked them accordingly to which steps they had fallen on.

Uhm, so very tempted to start talking in math...

But will restrain myself and cite Arrow in reasonably plain English

"Most systems are not going to work badly all of the time. All I proved is that all can work badly at times.

And exactly *what* is so amusing about this photo, young 'un? :laugh:

I don't care whether I actually understood 6.0, I *thought* I understood it, and that was good enough for me.

the cane is about to make an appearance ? hur hur
