Rating system for online games in Heroes of Might and Magic IV.

But if a person doesn't show up, as you say, they'll get a rating of 0, meaning their rating will remain the same... But if you introduce that coefficient k, the rating will decrease in case of absence.
If a player thinks: "Well, I'll skip it, and who cares, the rating will stay the same anyway," then in this case, the person won't sign up if they know they'll miss a few games – it won't be in their interest.

In other words, you're suggesting that you take a person who already has a rating of zero or some other number and push them into negative numbers with a formula? Is it worth the effort? Skipping a tournament, if you sign up and don't show up, puts the person in last place with ZERO points. The rating doesn't seem to change. But it doesn't increase either. Reducing the rating of such a player solves the problem of the rating "aging." Since there is no increase, the rating will decrease due to aging. Why add an additional coefficient that will even more ARTIFICIALLY, according to the whims of the system developers, push the player into additional negative numbers??? And if a person signed up with good intentions, but life didn't allow them to participate in the tournament – they didn't have enough real time? In this regard, your coefficient is not good. And if, with your good intentions, you offend even one such person because of the irresponsible ones, will that be right from a purely human point of view??? Start thinking from this position, and not from the position of how to punish the irresponsible even more. Ok?

I think the most interesting thing I posted was in the post about the formula for calculating. In principle, I don't understand the mathematical operation symbol "^" and the number 6000. Otherwise, my formula is somewhat similar to this one in a slightly simplified version.
P.S. Perhaps people play VGAplanet often, but not Heroes 4. There are few players, and not many tournaments, so a dynamic calculation is not needed.

:) If you had read everything I sent you. Sometimes one game lasts for HALF A YEAR!!! And each match involves no more than 11 people. The rating lists that I sent you contain a list of hundreds of people!!! What more is needed? The unclear symbol, I think, is the square root. The number 6000 – I don't know. I need help from mathematicians. I know some. These are AmberSoler and FireBall. Contact them directly in your own name for a consultation on this number in this formula! Only then can we finally decide whether it is suitable or not for Heroes online. Ask them for a consultation about this formula and whether it is suitable for online games – they won't charge you! ;) I think.
