Potential Tweaks to CFC Rating System
1. 6 regular games per day for U1200
Can we move this to a motion?
2. Varying k-factor k=48 for 800 graded to k=32 for 1600
Having a varying k-factor by rating makes sense. However, it would ideally not be a cut-off but graded over a wide rating range e.g. k=32 at 1600 linearly graded to k=48 at 800. Having a section cut off at the same point as the k-factor cutoff would lead to opponents having the same k-factor, which defeats the purpose.
3. Players gaining 200+ rating points in a single tournament
My personal observation is that some players earn too many bonus points in 7+ round tournaments, due to the fact that the threshold vs number of rounds is too flat. 29-point threshold for 5 rounds seems reasonable, but 39-point threshold for 9 rounds has to be too little. I would be interested in looking at the data to figure out if we can decrease the "13" but make the order on number of rounds higher than square root.
4. 2-Year 200-point floor?
A lifetime floor is unscientific and appears to be a last resort solution USCF adapted to combat sandbagging. Given that Canadian tournament don't tend to have large prizes, it doesn't seem necessary. However, as Aris mentioned, floors could encourage participation by seniors. A 2-year 200-point floor, for example, would still be scientific in the vast majority of cases.
Furthermore, a floor/insurance could be very valuable when OTB returns in 2021. An example would be no one can lose more than 100 points over the first 6 months of OTB.
5. Glicko
There are 2 drivers of higher k-factor ("rd") in Glicko - streaks and inactivity. The current bonus system already addresses streaks. The inactivity component is the tricky part because currently everyone in the rating pool is inactive. This is where identifying juniors as the inactive ones is beneficial because they are the ones likely to be improving away from OTB.

6. 2021 OTB Shock
Hi Vlad,
The return of OTB in 2021 will be the largest-ever one-time increase in the strength of the playing pool.
The quick incentive was a great idea but so far it is mostly juniors playing each other. Hoping to see more adults participate at those events - maybe the solution is to have a floor there? There also seem to be a dearth of 2000+ players there. Maybe the CFC can waive the rating fee on players over 2000, allowing organizers to offer them free entry?
