Now I see the difference

Thanks to the new update, I was able to see some of the games I played 3 years ago(I quit after that but decided it was not too late to start again.) I noticed nowadays the 1600 rated is different from that of 3 years ago. I saw how 1700 players still hang queens, 1400 falling for the scholar's (Happened multiple times)

When time passes, each rating group no doubtedly becomes stronger. 

This is not a joke, but I noticed I was playing way worse than I play now few years ago yet the rating is still similar. 

How interesting..

That is also why the number of grandmasters has gone from about 5 to more than 200

It is the people who use rybka or fritz or some other strong engine to assist in the games that throw the ratings off balance. Without any cheaters the rating system would be more accurate.
