Question about CFC rating changes

[Hugh Siddeley]

As Canada's weakest National Master I demand to know what happened during the rating of the Annex Chess Club Championship. How did I gain 147 points from 5 games?! And don't tell me it's from bonus points because I already used those up a long time ago. My reputation can't sustain such rating gains.

2284 2231 1963 2157 2065=10700.10700:-5=2140.
2140-1933=207.207x70%=144.9.144.9 2=146.9.
It looks like you got 2 bonus points.Congratulations.

As per example in the Chess.ca, the opponents rating average is not calculated for players with established ratings.
see http://chess.ca/handbook#section-4 and 425. SAMPLE CALCULATION

My calculations:

opponent	diff (Opponent - 1933)	Expected score	Actual
2231	298	0.15	1
2284	351	0.11	0
1963	30	0.46	0.5
2157	224	0.22	1
2065	132	0.32	1
.	.	.	.
.	Sum Expect	1.26 (Sx)	3.5 (S)

Then goes a formula

Rn = Ro (plus) 32 * (S - Sx) = 1933  (plus)  72 = 2005

As the final rating is 2080, total Bonus points were ~75. More than an actual rating gain :)
Was your coach B. Ivanov for this tournament? LOL

I love it when someone other than a kid earns some rating bonus points. Gives hope to the rest of us veterans.

As far as I'm concerned anyone under 55 is still a kid. :o

Which means they should be paying $ 30 instead of $ 48 if they are still treated as a kid ?

It would mean this if my prejudices as to who was a kid or not had any bearing on the CFC handbook rules. Alas for those seeking a discount my subjective feelings are not relevant to the CFC fees due.
