I'm probably around 1700-1800 *in my area* because in California I would not be close to that rating since the level of play there is much higher.
Can you statistically & mathematically prove that prove that ?
I mean your claim that the level of play there is much higher in California
Even if true , to me 1700 in Montana has to be same as 1700 Falkenberg
If not, there is a problem with ratings processing
David Marcus ( I believe he is a PhD at MIT and on faculty at MIT if am not mistaken) at Ratings Central uses measures of Standard Deviation in his rating but I am not sure what the geographic component , if any in that measure
