Rating double weighting rounds 1 & 2 instead of 2 & 3
"The most recent 25% of your rounds get double weighted"
I noticed that since rounds of a tournament are listed 1,2,3,4 instead of 4,3,2,1 a player rating can be higher or lower.
In my case I am rated about 934 since it took round 1 & 2 instead of 2 & 3 for double weighting which would give me about a 921.
I don't have that many rounds for rating, it is just something I noticed.
