If playa1 or garufalo are concerned about their ratings not reflecting their ability then they should play more games.
My point is that the Kleier ranking has been accepted for some time by the ISF.
The motivation is a fairer tournament due to more evenly matched groups by eliminating a small number of discrepancies where for example - a player is much more talented than their ELO suggests. (eg playa1)
There is also a basis to seed newcomers (eg Garulfo).
The ISF website is hosted by Kleier, so it would be damning if it did not use his rankings.
1. Tiebreak games are not counted in kleier ratings.
2. It assigns a 50 percent weight to tournaments from 2015, this is far too high.
3. The sample size is too small for a number of players for ratings to be accurate.
I am fine with using it if the methodology is published so that it can be reviewed.
