first, I apologize for a question that has been asked about a hundred times before...
does player "A" who is rated 3000 gain ANY rating points for beating play "B" who is rated 100 ? some websites might give a minimum of 1 rating point gain, others will allow zero point gain because of the difference at the beginning of the game.
Here at RHP is there a break off point where the higher rated player will gain ZERO points, even for a win? if so, what is that number (difference in ratings at start of the game) TY
I know the Q & A tells how to calculate the rating change after a game, but I'm surprised there isn't a chart
@mlb62 saidAs you say,all the calculations are there in faq.

Years ago,for my own amusement,I created my own spreadsheet to make a chart so I could plug in my and my opponents rating to see the effect of all results.
Now,I don't tend to bother with the ratings much.
As I said on a previous thread,they are based on current rating only which is affected by timeout.If a player loses a lot of games by timeout his rating will go down which then affects your rating when you finish your game against him.

thanks for the info, but surely there is a point reached ( difference of ratings) where the higher rate player will get zero points for a win. That number should be constant.
Also I remember talk of "Monkey Tools" or apps on this site that would display such information.
@mlb62 saidYes, that was Grease Monkey, and one of the RHP members had put together several useful Grease Monkey routines that worked with the RHP website back in the day.

One of those routines did show what the rating change outcome would be for both players for a particular game, based on a win, draw, or loss.
I think the Grease Monkey routines or scripts needed to be fixed whenever the RHP software was modified or upgraded.

Actually I’ve just noticed a further link in the thread above (a link to thread 80000), which says it is only applicable for players rated below 2100.
Which, if correct, would mean it’s no use to you as you're way above that. Sorry, maybe someone else can help.

hi and thanks... I went back to that post that had the rating chart. I'm perplexed by the idea that it applies to players rated 2100 and below. According to the chart, if Player "A" is rated 720 or more higher than player B at the end of the game, Player A will gain ZERO points for a win.
I have no clue as to why this rule wouldn't apply to everyone....what is important about 2100 level players?

@mlb62 saidI’ve just had a look in the section “How is my Rating Calculated” in the Site FAQ page, which can be accessed at the bottom of the page.

It states:
“Players are rated using the following formula:
New Rating = Old Rating + K * (Score - Win Expectancy)
K is a constant (32 for 0-2099, 24 for 2100-2399, 16 for 2400 and above)” .
So I presume this change in the value of K is why there is a difference.
What I don’t know, is why K changes from 32 to 24 for 2100-2399, and then to 16 for 2400+.
There must be a reason, but I’ll have to leave it to the more mathematically minded to answer that one I’m afraid.
