It's not that I am "scared" or math, rather that I dislike it intensely. It's all very well to say that everything could be calculated automatically, but I would feel compelled to verify changes myself, not so much because I am wary of deliberate cheating by those in charge of the system but because I am all to familiar with the mistakes and screw ups that abound wherever human beings are involved. I suspect that we all know of a number of occasions when people did not get ratings upgrades they earned because a tournament organizers did not send in results, or did not cross all the t's when they sent them in, or because there was a mix-up or omission upstream somewhere. I know two people who should be Cs right now but for such problems...and I was at the events where they got them and where the upgrades were announced at the medal presentations. An ELO-type system is not going to make such things stop happening. Hence I'd consider verification to be essential. And I would find being forced to do it very distasteful. I'm a fencer, Jim, not an accountant! I don't understand what makes people so eager to leap off a cliff to test the spiffy new pair of wings they just made themselves. Or why they are so keen on fixing what isn't broken.
