I explained it. If he doesn't show up, he'll get 0 points for each match in the tournament. In the end, he'll have a total of 0 points, which means he'll be in last place. Why now cram non-appearances into the rating formula when his rating will be calculated based on the PLACE he occupies? If you're having trouble deciphering the formula, that doesn't mean it's wrong. It's already been tested, and you have rating lists based on it for hundreds of people. But the fact that you're stuffing all sorts of things into the formula, but you supposedly understand perfectly well why it's needed, doesn't mean it's correct. At least because there are no real calculations, and then I tried to explain that all appearances and non-appearances will be taken into account if the formula only includes the PLACE parameter.
So, we're currently discussing the formula for non-appearances. I'll say this:
Why should his rating be calculated based on the place he occupied if he didn't even show up to the tournament, he just registered???. So, you can just register and bail, and his rating will be calculated, as if it just fell from the sky.
I'll say this: there are 2 formulas: one for calculating the rating, taking into account appearances, and another for calculating the rating for a player who didn't show up at all.
